Linda spent
25 of her money on 7 macarons and 4 wafers. If each macaron costs four times as much as a wafer, how many wafers could Linda buy with the rest of her money?
| |
Macarons |
Wafers |
| Number |
7 |
4 |
| Value |
4 u |
1 u |
| Total value |
28 u |
4 u |
Cost of 1 wafer = 1 u
Cost of 1 macaron = 4 u
Total cost of 7 macarons and 4 wafers
= 7 x 4 u + 4 x 1 u
= 32 u
Fraction of Linda's money left
= 1 -
25 =
3525 of Linda's money = 32 u
15 of Linda's money = 32 u ÷ 2 = 16 u
35 of Linda's money = 16 u x 3 = 48 u
Number of wafers that Linda could buy
= 48 u ÷ 1 u
= 48
Answer(s): 48
