Number of erasers that Henry had before = 9 u
Number of erasers that Henry gave to Reggie = 2 u
Number of erasers that Henry gave to Elijah = 3 u
Number of erasers that Henry gave to Tommy = 1 u
Number of erasers that Henry had left = 3 u
3 u = 12
1 u = 12 ÷ 3 = 4
Number of erasers that Henry had at first
= 9 u
= 9 u x 4
= 36
