25There were 76 more coats than windbreakers at first. If another 76 windbreakers were added at first, the number of windbreakers and coats would be the same.
5 u + 76 = 3 u + 64
5 u - 3 u = 64 - 76
2 u = -12
1 u = -12 ÷ 2 = -6
Number of windbreakers in the shop at first
= 5 u
= 5 x -6
= -30
Answer(s): -30
