37 of her money on 4 macarons and 10 puffs. If each macaron costs five times as much as a puff, how many macarons could Zara buy with the rest of her money?

Macarons |
Puffs |
| Number |
4 |
10 |
| Value |
5 u |
1 u |
| Total value |
20 u |
10 u |
Cost of 1 puff = 1 u
Cost of 1 macaron = 5 u
Total cost of 4 macarons and 10 puffs
= 4 x 5 u + 10 x 1 u
= 30 u
Fraction of Zara's money left
= 1 -
37 =
4737 of Zara's money = 30 u
17 of Zara's money = 30 u ÷ 3 = 10 u
47 of Zara's money = 10 u x 4 = 40 u
Number of macarons that Zara could buy
= 40 u ÷ 5 u
= 8
Answer(s): 8
