$1.90 |
|
| Total value |
1.4 u |
1.9 u + 13.3 |
1.9 u + 13.3 |
Amount that Jaslyn paid for the muffins
= 1 u x 1.40
= 1.4 u
Amount that Jaslyn paid for croissants
= 1.9 x (1 u + 7)
= 1.9 u + 13.3
Total amount that Jaslyn paid
= 1.4 u + 1.9 u + 13.3
= 3.3 u + 13.3
3.3 u + 13.3 = 26.5
3.3 u = 26.5 - 13.3
3.3 u = 13.2
1 u = 13.2 ÷ 3.3 = 4
Number of muffins that Jaslyn bought
= 1 u
= 4
Answer(s): 4
