After |
7 u - 69 |
9 u |
Nicole had 93 more stamps than Seth in the end. So, if Seth had another 93 stamps, he would have the same number of stamps as Nicole.
9 u = 7 u - 69 + 93
9 u - 7 u = 93 - 69
2 u = 24
1 u = 24 ÷ 2 = 12
Number of stamps that Nicole had at first
= 9 u
= 9 x 12
= 108
Answer: 108
