Shiyun spent
37 of her money on 10 macarons and 4 biscuits. If each macaron costs twice as much as a biscuit, how many biscuits could Shiyun buy with the rest of her money?
| |
Macarons |
Biscuits |
| Number |
10 |
4 |
| Value |
2 u |
1 u |
| Total value |
20 u |
4 u |
Cost of 1 biscuit = 1 u
Cost of 1 macaron = 2 u
Total cost of 10 macarons and 4 biscuits
= 10 x 2 u + 4 x 1 u
= 24 u
Fraction of Shiyun's money left
= 1 -
37 =
4737 of Shiyun's money = 24 u
17 of Shiyun's money = 24 u ÷ 3 = 8 u
47 of Shiyun's money = 8 u x 4 = 32 u
Number of biscuits that Shiyun could buy
= 32 u ÷ 1 u
= 32
Answer(s): 32
