Number of buttons that Ben had before = 10 u
Number of buttons that Ben gave to Asher = 1 u
Number of buttons that Ben gave to Neave = 1 u
Number of buttons that Ben gave to Tom = 3 u
Number of buttons that Ben had left = 5 u
5 u = 40
1 u = 40 ÷ 5 = 8
Number of buttons that Ben had at first
= 10 u
= 10 u x 8
= 80
