110There were 43 more jumpsuits than sweaters at first. If another 43 sweaters were added at first, the number of sweaters and jumpsuits would be the same.
10 u + 43 = 9 u + 53
10 u - 9 u = 53 - 43
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
