Wafers |
Tarts |
| Number |
4 |
8 |
| Value |
5 u |
1 u |
| Total value |
20 u |
8 u |
Cost of 1 tart = 1 u
Cost of 1 wafer = 5 u
Total cost of 4 wafers and 8 tarts
= 4 x 5 u + 8 x 1 u
= 28 u
Fraction of Olivia's money left
= 1 -
49 =
5949 of Olivia's money = 28 u
19 of Olivia's money = 28 u ÷ 4 = 7 u
59 of Olivia's money = 7 u x 5 = 35 u
Number of tarts that Olivia could buy
= 35 u ÷ 1 u
= 35
Answer(s): 35
