Zoe spent
811 of her money on 4 macarons and 8 cupcakes. If each macaron costs twice as much as a cupcake, how many macarons could Zoe buy with the rest of her money?

Macarons |
Cupcakes |
| Number |
4 |
8 |
| Value |
2 u |
1 u |
| Total value |
8 u |
8 u |
Cost of 1 cupcake = 1 u
Cost of 1 macaron = 2 u
Total cost of 4 macarons and 8 cupcakes
= 4 x 2 u + 8 x 1 u
= 16 u
Fraction of Zoe's money left
= 1 -
811 =
311811 of Zoe's money = 16 u
111 of Zoe's money = 16 u ÷ 8 = 2 u
311 of Zoe's money = 2 u x 3 = 6 u
Number of macarons that Zoe could buy
= 6 u ÷ 2 u
= 3
Answer(s): 3
