Pamela spent
25 of her money on 8 puffs and 10 croissants. If each puff costs five times as much as a croissant, how many puffs could Pamela buy with the rest of her money?

Puffs |
Croissants |
| Number |
8 |
10 |
| Value |
5 u |
1 u |
| Total value |
40 u |
10 u |
Cost of 1 croissant = 1 u
Cost of 1 puff = 5 u
Total cost of 8 puffs and 10 croissants
= 8 x 5 u + 10 x 1 u
= 50 u
Fraction of Pamela's money left
= 1 -
25 =
3525 of Pamela's money = 50 u
15 of Pamela's money = 50 u ÷ 2 = 25 u
35 of Pamela's money = 25 u x 3 = 75 u
Number of puffs that Pamela could buy
= 75 u ÷ 5 u
= 15
Answer(s): 15
