15There were 98 more vests than windbreakers at first. If another 98 windbreakers were added at first, the number of windbreakers and vests would be the same.
5 u + 98 = 4 u + 74
5 u - 4 u = 74 - 98
1 u = -24
1 u = -24 ÷ 1 = -24
Number of windbreakers in the shop at first
= 5 u
= 5 x -24
= -120
Answer(s): -120
