110There were 85 more sweaters than jumpsuits at first. If another 85 jumpsuits were added at first, the number of jumpsuits and sweaters would be the same.
10 u + 85 = 9 u + 67
10 u - 9 u = 67 - 85
1 u = -18
1 u = -18 ÷ 1 = -18
Number of jumpsuits in the shop at first
= 10 u
= 10 x -18
= -180
Answer(s): -180
