Jean spent
57 of her money on 8 cookies and 3 cupcakes. If each cookie costs four times as much as a cupcake, how many cupcakes could Jean buy with the rest of her money?
| |
Cookies |
Cupcakes |
| Number |
8 |
3 |
| Value |
4 u |
1 u |
| Total value |
32 u |
3 u |
Cost of 1 cupcake = 1 u
Cost of 1 cookie = 4 u
Total cost of 8 cookies and 3 cupcakes
= 8 x 4 u + 3 x 1 u
= 35 u
Fraction of Jean's money left
= 1 -
57 =
2757 of Jean's money = 35 u
17 of Jean's money = 35 u ÷ 5 = 7 u
27 of Jean's money = 7 u x 2 = 14 u
Number of cupcakes that Jean could buy
= 14 u ÷ 1 u
= 14
Answer(s): 14
