58 of her money on 3 puffs and 10 muffins. If each puff costs five times as much as a muffin, how many puffs could Victoria buy with the rest of her money?

Puffs |
Muffins |
| Number |
3 |
10 |
| Value |
5 u |
1 u |
| Total value |
15 u |
10 u |
Cost of 1 muffin = 1 u
Cost of 1 puff = 5 u
Total cost of 3 puffs and 10 muffins
= 3 x 5 u + 10 x 1 u
= 25 u
Fraction of Victoria's money left
= 1 -
58 =
3858 of Victoria's money = 25 u
18 of Victoria's money = 25 u ÷ 5 = 5 u
38 of Victoria's money = 5 u x 3 = 15 u
Number of puffs that Victoria could buy
= 15 u ÷ 5 u
= 3
Answer(s): 3
