Irene spent
49 of her money on 8 scones and 4 wafers. If each scone costs five times as much as a wafer, how many scones could Irene buy with the rest of her money?

Scones |
Wafers |
| Number |
8 |
4 |
| Value |
5 u |
1 u |
| Total value |
40 u |
4 u |
Cost of 1 wafer = 1 u
Cost of 1 scone = 5 u
Total cost of 8 scones and 4 wafers
= 8 x 5 u + 4 x 1 u
= 44 u
Fraction of Irene's money left
= 1 -
49 =
5949 of Irene's money = 44 u
19 of Irene's money = 44 u ÷ 4 = 11 u
59 of Irene's money = 11 u x 5 = 55 u
Number of scones that Irene could buy
= 55 u ÷ 5 u
= 11
Answer(s): 11
