| After |
5 u - 78 |
8 u |
Hazel had 99 more buttons than Luis in the end. So, if Luis had another 99 buttons, he would have the same number of buttons as Hazel.
8 u = 5 u - 78 + 99
8 u - 5 u = 99 - 78
3 u = 21
1 u = 21 ÷ 3 = 7
Number of buttons that Hazel had at first
= 8 u
= 8 x 7
= 56
Answer: 56
