Shiyun spent
35 of her money on 8 wafers and 4 cupcakes. If each wafer costs four times as much as a cupcake, how many wafers could Shiyun buy with the rest of her money?
| |
Wafers |
Cupcakes |
| Number |
8 |
4 |
| Value |
4 u |
1 u |
| Total value |
32 u |
4 u |
Cost of 1 cupcake = 1 u
Cost of 1 wafer = 4 u
Total cost of 8 wafers and 4 cupcakes
= 8 x 4 u + 4 x 1 u
= 36 u
Fraction of Shiyun's money left
= 1 -
35 =
2535 of Shiyun's money = 36 u
15 of Shiyun's money = 36 u ÷ 3 = 12 u
25 of Shiyun's money = 12 u x 2 = 24 u
Number of wafers that Shiyun could buy
= 24 u ÷ 4 u
= 6
Answer(s): 6
