0–4 launch: Have the class predict the effect of adding $10 once versus three times; do not show the total yet. 4–9 source: Read the Gym Index staff card and desk note, making the picture's three boxes distinct from evidence that the allowance repeats. 9–16 model: Regular 4×$30=$120; extra rate 1.25×$30=$37.50/hour. Put an allowance card outside the three-hour row. 16–27 independent route: A/B/C computes additional pay and total, then rewrites the card so an adult applicant can see the once-only condition. 27–32 audit: Compare the incorrect $262.50 obtained by repeating $10 for three hours with the correct $242.50. 32–35 exit: Name which unit $10 belongs to: per shift.
