Number of stamps that Eric had before = 9 u
Number of stamps that Eric gave to Jack = 2 u
Number of stamps that Eric gave to Tim = 2 u
Number of stamps that Eric gave to Will = 3 u
Number of stamps that Eric had left = 2 u
2 u = 10
1 u = 10 ÷ 2 = 5
Number of stamps that Eric had at first
= 9 u
= 9 u x 5
= 45
