Remember: Small pay later parts can pile into one big month. Pay later does not make things cheaper. It only moves the paying, so check the parts, the dates and any late fee.
Read and answer
Read the story first, then answer.
Dara's four small plansIn the pretend town of Lark Lane, Dara spotted a shirt for eight coins, and the shop said, "Pay later! Four equal parts, one a month, and the first today." Eight coins in four parts is two coins a part. Dara got twelve coins a month, so paying two felt like nothing, and the thought came, "Why not do it again?" In month two came a game for twelve coins, in four parts of three. In month three came headphones for sixteen coins, in four parts of four. In month four came a bag for four coins, in parts of just one, and one coin surely could not matter, but the other three plans were still running. All four bills arrived on the same day, two, three, four and one, and together they made one bill of ten coins, ten of Dara's twelve! That left Dara just two coins for everything else that month, and each bill looked small, so nobody had added them up. Pay later did not make anything cheaper. It only moved the paying later. Dara wrote every part on one calendar, so the hill of bills was easy to see.

The shirt costs 8 coins in 4 equal parts. Each ring is one part, so a part is coins.

Answer key · Set A
The pay-later pile-up
12 8 ÷ 4 = 2 coins a part.
25 2 + 3 = 5. The shirt's part and the game's part land together.
39 2 + 3 + 4 = 9.
410 coins 2 + 3 + 4 + 1 = 10. The other three plans are still running.
52 12 − 10 = 2.
61-C, 2-D, 3-B, 4-A Each price is split into 4 equal parts: 8 ÷ 4, 12 ÷ 4, 16 ÷ 4 and 4 ÷ 4.
740 coins 8 + 12 + 16 + 4 = 40. Pay later does not lower a price.
81, 3, 4, 2 First the shirt, then the game, then the headphones, and last the bag.
9Splits a price into small parts, Moves the paying to later months, Lets plans overlap into one month Pay later splits a price, moves the paying later and lets parts pile into one month. It does not lower a price or stop the bill.
10No The bag moves month 4 from 9 to 10, leaving Dara only 2 coins.
111 2 + 5 + 9 + 10 + 8 + 5 = 39, and 40 − 39 = 1.
