14There were 52 more dresses than windbreakers at first. If another 52 windbreakers were added at first, the number of windbreakers and dresses would be the same.
4 u + 52 = 3 u + 82
4 u - 3 u = 82 - 52
1 u = 30
1 u = 30 ÷ 1 = 30
Number of windbreakers in the shop at first
= 4 u
= 4 x 30
= 120
Answer(s): 120
