15There were 43 more coats than windbreakers at first. If another 43 windbreakers were added at first, the number of windbreakers and coats would be the same.
5 u + 43 = 4 u + 58
5 u - 4 u = 58 - 43
1 u = 15
1 u = 15 ÷ 1 = 15
Number of windbreakers in the shop at first
= 5 u
= 5 x 15
= 75
Answer(s): 75
