Gwen spent
37 of her money on 5 cupcakes and 8 biscuits. If each cupcake costs twice as much as a biscuit, how many cupcakes could Gwen buy with the rest of her money?
| |
Cupcakes |
Biscuits |
| Number |
5 |
8 |
| Value |
2 u |
1 u |
| Total value |
10 u |
8 u |
Cost of 1 biscuit = 1 u
Cost of 1 cupcake = 2 u
Total cost of 5 cupcakes and 8 biscuits
= 5 x 2 u + 8 x 1 u
= 18 u
Fraction of Gwen's money left
= 1 -
37 =
4737 of Gwen's money = 18 u
17 of Gwen's money = 18 u ÷ 3 = 6 u
47 of Gwen's money = 6 u x 4 = 24 u
Number of cupcakes that Gwen could buy
= 24 u ÷ 2 u
= 12
Answer(s): 12
