Elyse spent
47 of her money on 5 shortbreads and 6 puffs. If each shortbread costs twice as much as a puff, how many shortbreads could Elyse buy with the rest of her money?
| |
Shortbreads |
Puffs |
| Number |
5 |
6 |
| Value |
2 u |
1 u |
| Total value |
10 u |
6 u |
Cost of 1 puff = 1 u
Cost of 1 shortbread = 2 u
Total cost of 5 shortbreads and 6 puffs
= 5 x 2 u + 6 x 1 u
= 16 u
Fraction of Elyse's money left
= 1 -
47 =
3747 of Elyse's money = 16 u
17 of Elyse's money = 16 u ÷ 4 = 4 u
37 of Elyse's money = 4 u x 3 = 12 u
Number of shortbreads that Elyse could buy
= 12 u ÷ 2 u
= 6
Answer(s): 6
