110There were 75 more jumpsuits than skirts at first. If another 75 skirts were added at first, the number of skirts and jumpsuits would be the same.
10 u + 75 = 9 u + 64
10 u - 9 u = 64 - 75
1 u = -11
1 u = -11 ÷ 1 = -11
Number of skirts in the shop at first
= 10 u
= 10 x -11
= -110
Answer(s): -110
