14There were 66 more skirts than windbreakers at first. If another 66 windbreakers were added at first, the number of windbreakers and skirts would be the same.
4 u + 66 = 3 u + 67
4 u - 3 u = 67 - 66
1 u = 1
1 u = 1 ÷ 1 = 1
Number of windbreakers in the shop at first
= 4 u
= 4 x 1
= 4
Answer(s): 4
