Number of stamps that Brandon had before = 6 u
Number of stamps that Brandon gave to Flynn = 1 u
Number of stamps that Brandon gave to Bryan = 1 u
Number of stamps that Brandon gave to Perry = 1 u
Number of stamps that Brandon had left = 3 u
3 u = 15
1 u = 15 ÷ 3 = 5
Number of stamps that Brandon had at first
= 6 u
= 6 u x 5
= 30
