25 of her money on 4 puffs and 6 biscuits. If each puff costs five times as much as a biscuit, how many biscuits could Abi buy with the rest of her money?

Puffs |
Biscuits |
| Number |
4 |
6 |
| Value |
5 u |
1 u |
| Total value |
20 u |
6 u |
Cost of 1 biscuit = 1 u
Cost of 1 puff = 5 u
Total cost of 4 puffs and 6 biscuits
= 4 x 5 u + 6 x 1 u
= 26 u
Fraction of Abi's money left
= 1 -
25 =
3525 of Abi's money = 26 u
15 of Abi's money = 26 u ÷ 2 = 13 u
35 of Abi's money = 13 u x 3 = 39 u
Number of biscuits that Abi could buy
= 39 u ÷ 1 u
= 39
Answer(s): 39
