110There were 66 more blazers than jumpsuits at first. If another 66 jumpsuits were added at first, the number of jumpsuits and blazers would be the same.
10 u + 66 = 9 u + 89
10 u - 9 u = 89 - 66
1 u = 23
1 u = 23 ÷ 1 = 23
Number of jumpsuits in the shop at first
= 10 u
= 10 x 23
= 230
Answer(s): 230
