|
| Total value |
1.9 u |
1.5 u + 7.5 |
1.5 u + 7.5 |
Amount that Gabby paid for the croissants
= 1 u x 1.90
= 1.9 u
Amount that Gabby paid for scones
= 1.5 x (1 u + 5)
= 1.5 u + 7.5
Total amount that Gabby paid
= 1.9 u + 1.5 u + 7.5
= 3.4 u + 7.5
3.4 u + 7.5 = 27.9
3.4 u = 27.9 - 7.5
3.4 u = 20.4
1 u = 20.4 ÷ 3.4 = 6
Number of croissants that Gabby bought
= 1 u
= 6
Answer(s): 6
