310 of her money on 7 macarons and 10 croissants. If each macaron costs five times as much as a croissant, how many croissants could Gwen buy with the rest of her money?

| Number |

10 |
| Value |
5 u |
1 u |
| Total value |
35 u |
10 u |
Cost of 1 croissant = 1 u
Cost of 1 macaron = 5 u
Total cost of 7 macarons and 10 croissants
= 7 x 5 u + 10 x 1 u
= 45 u
Fraction of Gwen's money left
= 1 -
310 =
710310 of Gwen's money = 45 u
110 of Gwen's money = 45 u ÷ 3 = 15 u
710 of Gwen's money = 15 u x 7 = 105 u
Number of croissants that Gwen could buy
= 105 u ÷ 1 u
= 105
Answer(s): 105
