Emily spent
27 of her money on 8 wafers and 6 cookies. If each wafer costs five times as much as a cookie, how many wafers could Emily buy with the rest of her money?

Wafers |
Cookies |
| Number |
8 |
6 |
| Value |
5 u |
1 u |
| Total value |
40 u |
6 u |
Cost of 1 cookie = 1 u
Cost of 1 wafer = 5 u
Total cost of 8 wafers and 6 cookies
= 8 x 5 u + 6 x 1 u
= 46 u
Fraction of Emily's money left
= 1 -
27 =
5727 of Emily's money = 46 u
17 of Emily's money = 46 u ÷ 2 = 23 u
57 of Emily's money = 23 u x 5 = 115 u
Number of wafers that Emily could buy
= 115 u ÷ 5 u
= 23
Answer(s): 23
