59 of her money on 9 cupcakes and 7 tarts. If each cupcake costs twice as much as a tart, how many cupcakes could Victoria buy with the rest of her money?

Cupcakes |
Tarts |
| Number |
9 |
7 |
| Value |
2 u |
1 u |
| Total value |
18 u |
7 u |
Cost of 1 tart = 1 u
Cost of 1 cupcake = 2 u
Total cost of 9 cupcakes and 7 tarts
= 9 x 2 u + 7 x 1 u
= 25 u
Fraction of Victoria's money left
= 1 -
59 =
4959 of Victoria's money = 25 u
19 of Victoria's money = 25 u ÷ 5 = 5 u
49 of Victoria's money = 5 u x 4 = 20 u
Number of cupcakes that Victoria could buy
= 20 u ÷ 2 u
= 10
Answer(s): 10
