|
| Total value |
1.8 u |
1.1 u + 8.8 |
0.7 u - 8.8 |
Amount that Jaslyn paid for the cupcakes
= 1 u x 1.8
= 1.8 u
Amount that Jaslyn paid for the wafers
= 1.1 x (1 u + 8)
= 1.1 u + 8.8
Amount that Jaslyn paid less on the wafers than the cupcakes
= 1.8 u - (1.1 u + 8.8)
= 1.8 u - 1.1 u - 8.8
= 0.7 u - 8.8
0.7 u - 8.8 = 25.50
0.7 u = 25.50 + 8.8
0.7 u = 34.3
1 u = 34.3 ÷ 0.7 = 49
Number of wafers that Jaslyn bought
= 1 u + 8
= 49 + 8
= 57
Answer(s): 57
