Shannon spent
25 of her money on 7 scones and 4 cupcakes. If each scone costs twice as much as a cupcake, how many cupcakes could Shannon buy with the rest of her money?

Scones |
Cupcakes |
| Number |
7 |
4 |
| Value |
2 u |
1 u |
| Total value |
14 u |
4 u |
Cost of 1 cupcake = 1 u
Cost of 1 scone = 2 u
Total cost of 7 scones and 4 cupcakes
= 7 x 2 u + 4 x 1 u
= 18 u
Fraction of Shannon's money left
= 1 -
25 =
3525 of Shannon's money = 18 u
15 of Shannon's money = 18 u ÷ 2 = 9 u
35 of Shannon's money = 9 u x 3 = 27 u
Number of cupcakes that Shannon could buy
= 27 u ÷ 1 u
= 27
Answer(s): 27
