Fiona spent
37 of her money on 6 shortbreads and 3 croissants. If each shortbread costs twice as much as a croissant, how many shortbreads could Fiona buy with the rest of her money?
| |
Shortbreads |
Croissants |
| Number |
6 |
3 |
| Value |
2 u |
1 u |
| Total value |
12 u |
3 u |
Cost of 1 croissant = 1 u
Cost of 1 shortbread = 2 u
Total cost of 6 shortbreads and 3 croissants
= 6 x 2 u + 3 x 1 u
= 15 u
Fraction of Fiona's money left
= 1 -
37 =
4737 of Fiona's money = 15 u
17 of Fiona's money = 15 u ÷ 3 = 5 u
47 of Fiona's money = 5 u x 4 = 20 u
Number of shortbreads that Fiona could buy
= 20 u ÷ 2 u
= 10
Answer(s): 10
