Every maker, company, person, caption, price, exchange rate, wage, figure and event below is fictional; $ means a model Australian dollar unless USD is named. Public lines are invented texts for analysis, and desk notes are separate constructed evidence, not real receipts, interviews or photographs. These are not pay, currency, investment, tax or purchasing advice. Read or transform the complete text into the learner's chosen access mode; log source access without collecting personal financial or identity data. For each pair ask: Who is foregrounded? Which number and unit are actually supported? What remains outside the frame? The public formative checks use new cases.
Day 21 · Clockwork Museum label shift
Public caption: A fictional museum editor writes to newsletter readers, “Two late hours built the whole display. The label maker took home $275 because they stayed.” The imaginary illustration shows only a gloved hand at a label press; it cannot identify every contributor.
Desk note: One invented adult gross-pay model has 7 regular hours at $26/hour, 2 additional hours at 1.5 times the base hourly rate, and a $15 allowance once for the shift. No actual award, deduction, take-home amount, completed exhibit or contribution ranking is known.
Inquiry: Find each gross-pay layer and the total. Explain how two late hours and the cropped hand foreground one part while the base hours and allowance remain visible in the note. Revise the caption within the model.
Day 22 · Gym equipment index
Public staff card: A fictional equipment-index editor writes, “Our $10 allowance adds $10 to every extra hour. Every extra hour pays the same as a full regular hour plus that bonus.” A line drawing shows three extra-hour boxes, but the caption gives no pay-rule evidence on its own.
Desk note: One invented adult shift: 4 regular hours at $30/hour, 3 additional hours at 1.25 times the base hourly rate, and one $10 allowance for the entire shift. No real gym worker, award, tax, eligibility or take-home pay is described.
Inquiry: Calculate regular pay, each additional-hour rate, additional-hours pay and total gross model pay. Show why repeating the once-only allowance changes the result, and replace the public line.
Day 23 · Cycling clue badges
Public catalogue: A fictional puzzle-route publisher tells adult buyers, “Our badges carry a 25% margin. That is a quarter of each $70 sale for the project.” The pictured route arrow is an invented icon, not a safe real-world cycle route.
Desk note: One badge has a $56 stated production cost and a $70 stated sale price. The dollar gap is before all other expenses or tax. Mark-up uses cost as its base; gross price margin uses sale price as its base. No actual profit or beneficiary allocation is established.
Inquiry: Calculate the dollar gap, mark-up percentage and gross price margin percentage. Identify the public sentence's shifted base and write a narrower explanation.
Day 24 · Quiet-space paper panels
Public update: A fictional display team posts two cropped price cards, one marked “before” and one “after”: “The cost went up 25%, so another 25% down will put us exactly where we began.” The crop gives no explanation of what changed beyond the two numbers.
Desk note: In this constructed price model, a paper panel goes from $96 to $120. No quantity, supplier, material quality, accessibility effect or actual sale is known. Compare a 25% rise on the first base with the percentage decrease needed from $120 to return to $96.
Inquiry: Show both percentage bases; test the claimed cancellation and revise the cropped update. The panel is not an access solution tested with users.
Day 25 · Tabletop maker-fair ledger
Public summary: A fictional fair organiser writes to supporters, “Every dollar of our $320 sales goes straight to the makers.” An imagined close-crop shows a maker's hands holding one paper puzzle but leaves the cost ledger outside the frame.
Desk note: The invented fair sold 40 paper puzzles at $8 each, giving $320 gross receipts. Stated costs are $125 stock, $45 table fee and $100 adult help. Other costs and how money is allocated after these entries are unknown; this is not a real fundraiser or wage record.
Inquiry: Compute the known remainder after the three stated costs, distinguish revenue from an allocation to makers, and revise the summary without claiming what happened to the remainder. A separate fresh Check A follows this lesson if the teacher schedules it.
Day 26 · Mobile science-display board
Public image caption: A fictional exhibit editor describes a picture showing a $48 label while the earlier label is outside the crop: “A 20% cut brings the price down; a 20% rise will restore the original. The display is back where it started.” There is no real photograph or science measurement.
Desk note: One invented board price starts at $60, falls 20% of $60 to $48, then asks what percentage of $48 would return it to $60. No fee, tax, product quality, actual buyer or future price is supplied.
Inquiry: Calculate the decrease and return increase. Explain what the crop and repeated 20% conceal about the two bases.
Day 27 · Animation sound-cue licence
Public brochure: A fictional media club editor tells international readers, “USD $84 is the same as AUD $84, so you can swap the dollar sign and keep the number.” The designed brochure prints the two currency symbols in the same type size to make them look parallel.
Desk note: For a purely invented arithmetic rate, assume AUD $1 = USD $0.70, no fee or spread. Convert AUD $240 to USD and USD $84 to AUD. This is not a current or historical exchange quote, licence price or transaction.
Inquiry: Show conversion direction and reverse check, then write a brochure line that does not equate different units or promise a real rate.
Day 28 · Kite Ledger paper-company flyer
Public flyer: Fictional Kite Ledger Ltd addresses imagined investors: “Buy 40 shares and receive $36 every year, forever. Our 3% dividend is a promise.” The flyer foregrounds one model year in a large box and leaves later years blank.
Desk note: The invented share price is $30 per share, the stipulated one-year dividend is $0.90 per share, and a model portfolio holds 40 shares. No future dividends, share-price change, fees or investor suitability is supplied. ASIC MoneySmart explains that dividends are not guaranteed in real life; this source only sets a boundary, not advice.
Inquiry: Calculate that one-year portfolio dividend and dividend yield on the stipulated price; replace forever and promise with a sourced one-year statement.
Day 29 · Two model companies, one headline
Public chart caption: A fictional finance-magazine editor places Tinpath's $36 share-price bar shorter than Hearthtile's $48 bar and writes, “Tinpath is the better-value company because its share costs less.” The imagined bars show prices only, not earnings or risk.
Desk note: Fictional Tinpath has $36 price per share and $3 annual earnings per share. Fictional Hearthtile has $48 price per share and $4 annual earnings per share. Use P/E = price per share ÷ annual earnings per share. No dividend, asset value, future earnings, risk, market data or recommendation is known.
Inquiry: Calculate and compare both P/E ratios, then revise the headline so the numerical conclusion does not rank the companies as investments.
Day 30 · Soundwheel's two percentages
Public explainer: Fictional Soundwheel Papers publishes a one-panel infographic: “Our P/E of 10 means a 10% annual cash dividend. Ten is ten—no extra calculation needed.” A ten-segment ring visually makes ratio and percent look interchangeable.
Desk note: One invented share has $20 price, $2 annual earnings per share, and a stipulated one-year dividend of $0.60 per share. Use P/E = price ÷ earnings per share and dividend yield = dividend per share ÷ share price × 100%. Future dividends, costs and real investment value are unknown.
Inquiry: Calculate the ratio and yield separately, explain the infographic's unit confusion, and publish a careful correction. A separate fresh Check B follows if scheduled.
