15There were 50 more windbreakers than blouses at first. If another 50 blouses were added at first, the number of blouses and windbreakers would be the same.
5 u + 50 = 4 u + 89
5 u - 4 u = 89 - 50
1 u = 39
1 u = 39 ÷ 1 = 39
Number of blouses in the shop at first
= 5 u
= 5 x 39
= 195
Answer(s): 195
