14There were 86 more sweaters than jumpsuits at first. If another 86 jumpsuits were added at first, the number of jumpsuits and sweaters would be the same.
4 u + 86 = 3 u + 100
4 u - 3 u = 100 - 86
1 u = 14
1 u = 14 ÷ 1 = 14
Number of jumpsuits in the shop at first
= 4 u
= 4 x 14
= 56
Answer(s): 56
