| Total value |
4 u |
5 u + 15 |
9 u + 15 |
Cost of 1 cardigan = 1 u
Cost of 4 cardigans = 4 u
Cost of 1 blouse = 1 u + 3
Cost of 5 blouses
= 5 x (1 u + 3)
= 5 u + 15
Cost of 4 cardigans and 5 blouses
= 4 u + 5 u + 15
= 9 u + 15
9 u + 15 = 294
9 u = 294 - 15
9 u = 279
1 u = 279 ÷ 9 = 31
Cost of 1 blouse
= 31 + 3
= $34
Answer(s): $34
