Victoria spent
47 of her money on 8 shortbreads and 4 biscuits. If each shortbread costs twice as much as a biscuit, how many biscuits could Victoria buy with the rest of her money?

Shortbreads |
Biscuits |
| Number |
8 |
4 |
| Value |
2 u |
1 u |
| Total value |
16 u |
4 u |
Cost of 1 biscuit = 1 u
Cost of 1 shortbread = 2 u
Total cost of 8 shortbreads and 4 biscuits
= 8 x 2 u + 4 x 1 u
= 20 u
Fraction of Victoria's money left
= 1 -
47 =
3747 of Victoria's money = 20 u
17 of Victoria's money = 20 u ÷ 4 = 5 u
37 of Victoria's money = 5 u x 3 = 15 u
Number of biscuits that Victoria could buy
= 15 u ÷ 1 u
= 15
Answer(s): 15
