Wendy had 53 less buttons than Jade in the end. So, if Wendy had another 53 buttons in the end, the number of buttons that Wendy and Jade each had would be the same.
12 u + 18 = 5 u + 53
12 u - 5 u = 53 - 18
7 u = 35
1 u = 35 ÷ 7 = 5
Number of buttons that Jade had in the end
= 12 u + 18
= 12 x 5 + 18
= 60 + 18
= 78
Answer(s): 78
