6 |
| Value |
3 u |
1 u |
| Total value |
12 u |
6 u |
Cost of 1 croissant = 1 u
Cost of 1 macaron = 3 u
Total cost of 4 macarons and 6 croissants
= 4 x 3 u + 6 x 1 u
= 18 u
Fraction of Gillian's money left
= 1 -
38 =
5838 of Gillian's money = 18 u
18 of Gillian's money = 18 u ÷ 3 = 6 u
58 of Gillian's money = 6 u x 5 = 30 u
Number of macarons that Gillian could buy
= 30 u ÷ 3 u
= 10
