110There were 54 more sweaters than jumpsuits at first. If another 54 jumpsuits were added at first, the number of jumpsuits and sweaters would be the same.
10 u + 54 = 9 u + 88
10 u - 9 u = 88 - 54
1 u = 34
1 u = 34 ÷ 1 = 34
Number of jumpsuits in the shop at first
= 10 u
= 10 x 34
= 340
Answer(s): 340
