Natalie spent
25 of her money on 3 biscuits and 4 cupcakes. If each biscuit costs four times as much as a cupcake, how many biscuits could Natalie buy with the rest of her money?

Biscuits |
Cupcakes |
| Number |
3 |
4 |
| Value |
4 u |
1 u |
| Total value |
12 u |
4 u |
Cost of 1 cupcake = 1 u
Cost of 1 biscuit = 4 u
Total cost of 3 biscuits and 4 cupcakes
= 3 x 4 u + 4 x 1 u
= 16 u
Fraction of Natalie's money left
= 1 -
25 =
3525 of Natalie's money = 16 u
15 of Natalie's money = 16 u ÷ 2 = 8 u
35 of Natalie's money = 8 u x 3 = 24 u
Number of biscuits that Natalie could buy
= 24 u ÷ 4 u
= 6
Answer(s): 6
