| Number |
5 |
3 |
| Value |
5 u |
1 u |
| Total value |
25 u |
3 u |
Cost of 1 biscuit = 1 u
Cost of 1 tart = 5 u
Total cost of 5 tarts and 3 biscuits
= 5 x 5 u + 3 x 1 u
= 28 u
Fraction of Julie's money left
= 1 -
49 =
5949 of Julie's money = 28 u
19 of Julie's money = 28 u ÷ 4 = 7 u
59 of Julie's money = 7 u x 5 = 35 u
Number of biscuits that Julie could buy
= 35 u ÷ 1 u
= 35
Answer(s): 35
