1 u |
1 u + 11 |
|
| Total value |
5 u |
3 u + 33 |
8 u + 33 |
Cost of 1 cardigan = 1 u
Cost of 5 cardigans = 5 u
Cost of 1 blouse = 1 u + 11
Cost of 3 blouses
= 3 x (1 u + 11)
= 3 u + 33
Cost of 5 cardigans and 3 blouses
= 5 u + 3 u + 33
= 8 u + 33
8 u + 33 = 177
8 u = 177 - 33
8 u = 144
1 u = 144 ÷ 8 = 18
Cost of 1 blouse
= 18 + 11
= $29
Answer(s): $29
