27 of her money on 4 wafers and 10 cupcakes. If each wafer costs five times as much as a cupcake, how many cupcakes could Nicole buy with the rest of her money?

Wafers |
Cupcakes |
| Number |
4 |
10 |
| Value |
5 u |
1 u |
| Total value |
20 u |
10 u |
Cost of 1 cupcake = 1 u
Cost of 1 wafer = 5 u
Total cost of 4 wafers and 10 cupcakes
= 4 x 5 u + 10 x 1 u
= 30 u
Fraction of Nicole's money left
= 1 -
27 =
5727 of Nicole's money = 30 u
17 of Nicole's money = 30 u ÷ 2 = 15 u
57 of Nicole's money = 15 u x 5 = 75 u
Number of cupcakes that Nicole could buy
= 75 u ÷ 1 u
= 75
Answer(s): 75
