25 of her money on 7 scones and 5 biscuits. If each scone costs five times as much as a biscuit, how many biscuits could Rachel buy with the rest of her money?

| Number |
7 |
5 |
| Value |
5 u |
1 u |
| Total value |
35 u |
5 u |
Cost of 1 biscuit = 1 u
Cost of 1 scone = 5 u
Total cost of 7 scones and 5 biscuits
= 7 x 5 u + 5 x 1 u
= 40 u
Fraction of Rachel's money left
= 1 -
25 =
3525 of Rachel's money = 40 u
15 of Rachel's money = 40 u ÷ 2 = 20 u
35 of Rachel's money = 20 u x 3 = 60 u
Number of biscuits that Rachel could buy
= 60 u ÷ 1 u
= 60
Answer(s): 60
