| Number |
9 |
6 |
| Value |
2 u |
1 u |
| Total value |
18 u |
6 u |
Cost of 1 macaron = 1 u
Cost of 1 scone = 2 u
Total cost of 9 scones and 6 macarons
= 9 x 2 u + 6 x 1 u
= 24 u
Fraction of Victoria's money left
= 1 -
29 =
7929 of Victoria's money = 24 u
19 of Victoria's money = 24 u ÷ 2 = 12 u
79 of Victoria's money = 12 u x 7 = 84 u
Number of scones that Victoria could buy
= 84 u ÷ 2 u
= 42
Answer(s): 42
