Total value |
2.5 u |
1.1 u + 8.8 |
3.6 u + 8.8 |
Amount that Mrs Sher paid for strawberry cupcakes
= 1 u x 2.50
= 2.5 u
Amount that Mrs Sher paid for apple cupcakes
= 1.10 x (1 u + 8)
= 1.1 u + 8.8
Total amount that Mrs Sher paid
= 2.5 u + 1.1 u + 8.8
= 3.6 u + 8.8
3.6 u + 8.8= 16
3.6 u = 16 - 8.8
3.6 u = 7.2
1 u = 7.2 ÷ 3.6 = 2
Number of cupcakes that Mrs Sher bought altogether
= 2 u + 8
= 2 x 2 + 8
= 4 + 8
= 12
Answer(s): 12
