110There were 68 more vests than sweaters at first. If another 68 sweaters were added at first, the number of sweaters and vests would be the same.
10 u + 68 = 9 u + 58
10 u - 9 u = 58 - 68
1 u = -10
1 u = -10 ÷ 1 = -10
Number of sweaters in the shop at first
= 10 u
= 10 x -10
= -100
Answer(s): -100
