Cookies |
Cupcakes |
| Number |
3 |
6 |
| Value |
5 u |
1 u |
| Total value |
15 u |
6 u |
Cost of 1 cupcake = 1 u
Cost of 1 cookie = 5 u
Total cost of 3 cookies and 6 cupcakes
= 3 x 5 u + 6 x 1 u
= 21 u
Fraction of Jane's money left
= 1 -
311 =
811311 of Jane's money = 21 u
111 of Jane's money = 21 u ÷ 3 = 7 u
811 of Jane's money = 7 u x 8 = 56 u
Number of cupcakes that Jane could buy
= 56 u ÷ 1 u
= 56
Answer(s): 56
