Raeann spent
47 of her money on 10 cupcakes and 4 cookies. If each cupcake costs twice as much as a cookie, how many cupcakes could Raeann buy with the rest of her money?
| |
Cupcakes |
Cookies |
| Number |
10 |
4 |
| Value |
2 u |
1 u |
| Total value |
20 u |
4 u |
Cost of 1 cookie = 1 u
Cost of 1 cupcake = 2 u
Total cost of 10 cupcakes and 4 cookies
= 10 x 2 u + 4 x 1 u
= 24 u
Fraction of Raeann's money left
= 1 -
47 =
3747 of Raeann's money = 24 u
17 of Raeann's money = 24 u ÷ 4 = 6 u
37 of Raeann's money = 6 u x 3 = 18 u
Number of cupcakes that Raeann could buy
= 18 u ÷ 2 u
= 9
Answer(s): 9
