1 u |
1 u + 11 |
|
| Total value |
4 u |
3 u + 33 |
7 u + 33 |
Cost of 1 cardigan = 1 u
Cost of 4 cardigans = 4 u
Cost of 1 blouse = 1 u + 11
Cost of 3 blouses
= 3 x (1 u + 11)
= 3 u + 33
Cost of 4 cardigans and 3 blouses
= 4 u + 3 u + 33
= 7 u + 33
7 u + 33 = 292
7 u = 292 - 33
7 u = 259
1 u = 259 ÷ 7 = 37
Cost of 1 blouse
= 37 + 11
= $48
Answer(s): $48
