14There were 92 more coats than windbreakers at first. If another 92 windbreakers were added at first, the number of windbreakers and coats would be the same.
4 u + 92 = 3 u + 55
4 u - 3 u = 55 - 92
1 u = -37
1 u = -37 ÷ 1 = -37
Number of windbreakers in the shop at first
= 4 u
= 4 x -37
= -148
Answer(s): -148
