310There were 43 more windbreakers than sweaters at first. If another 43 sweaters were added at first, the number of sweaters and windbreakers would be the same.
10 u + 43 = 7 u + 88
10 u - 7 u = 88 - 43
3 u = 45
1 u = 45 ÷ 3 = 15
Number of sweaters in the shop at first
= 10 u
= 10 x 15
= 150
Answer(s): 150
