15There were 73 more jumpsuits than windbreakers at first. If another 73 windbreakers were added at first, the number of windbreakers and jumpsuits would be the same.
5 u + 73 = 4 u + 82
5 u - 4 u = 82 - 73
1 u = 9
1 u = 9 ÷ 1 = 9
Number of windbreakers in the shop at first
= 5 u
= 5 x 9
= 45
Answer(s): 45
