14There were 82 more dresses than windbreakers at first. If another 82 windbreakers were added at first, the number of windbreakers and dresses would be the same.
4 u + 82 = 3 u + 53
4 u - 3 u = 53 - 82
1 u = -29
1 u = -29 ÷ 1 = -29
Number of windbreakers in the shop at first
= 4 u
= 4 x -29
= -116
Answer(s): -116
