Macarons |
Cupcakes |
| Number |
7 |
8 |
| Value |
2 u |
1 u |
| Total value |
14 u |
8 u |
Cost of 1 cupcake = 1 u
Cost of 1 macaron = 2 u
Total cost of 7 macarons and 8 cupcakes
= 7 x 2 u + 8 x 1 u
= 22 u
Fraction of Tammy's money left
= 1 -
211 =
911211 of Tammy's money = 22 u
111 of Tammy's money = 22 u ÷ 2 = 11 u
911 of Tammy's money = 11 u x 9 = 99 u
Number of cupcakes that Tammy could buy
= 99 u ÷ 1 u
= 99
Answer(s): 99
