Open only when your teacher starts the Day 10 check. This is a new fictional source. The prices are invented and delivery, storage and future use have not been priced.
Source: imaginary Story Shelf bookmark supplier newsletter. The large headline is followed by the supplier's small print.
“The bigger bundle always saves your project money.”
Six bookmarks cost $13.20. Nine bookmarks cost $19.35. These prices are for unopened whole bundles; the supplier does not sell part bundles or promise returns for unused bookmarks. Delivery is excluded. One student organiser needs exactly six bookmarks today; another needs exactly eighteen. Nobody has supplied storage space, future demand or delivery cost.
Write 80–120 words, or an agreed equivalent, for a fictional student project group. Explain how always positions a reader. Compare enough whole bundles for six bookmarks and for eighteen bookmarks. Show the price calculations, identify one unknown and offer a bounded recommendation or question. You may use a calculator if your teacher permits it; record your working and units.
