Number of buttons that Howard had before = 11 u
Number of buttons that Howard gave to Bryan = 1 u
Number of buttons that Howard gave to Asher = 3 u
Number of buttons that Howard gave to Rael = 3 u
Number of buttons that Howard had left = 4 u
4 u = 20
1 u = 20 ÷ 4 = 5
Number of buttons that Howard had at first
= 11 u
= 11 u x 5
= 55
