Raeann spent
25 of her money on 8 biscuits and 10 macarons. If each biscuit costs five times as much as a macaron, how many biscuits could Raeann buy with the rest of her money?

Biscuits |
Macarons |
| Number |
8 |
10 |
| Value |
5 u |
1 u |
| Total value |
40 u |
10 u |
Cost of 1 macaron = 1 u
Cost of 1 biscuit = 5 u
Total cost of 8 biscuits and 10 macarons
= 8 x 5 u + 10 x 1 u
= 50 u
Fraction of Raeann's money left
= 1 -
25 =
3525 of Raeann's money = 50 u
15 of Raeann's money = 50 u ÷ 2 = 25 u
35 of Raeann's money = 25 u x 3 = 75 u
Number of biscuits that Raeann could buy
= 75 u ÷ 5 u
= 15
Answer(s): 15
