Number of erasers that Gabriel had before = 5 u
Number of erasers that Gabriel gave to Wesley = 1 u
Number of erasers that Gabriel gave to Pierre = 1 u
Number of erasers that Gabriel gave to Ken = 1 u
Number of erasers that Gabriel had left = 2 u
2 u = 28
1 u = 28 ÷ 2 = 14
Number of erasers that Gabriel had at first
= 5 u
= 5 u x 14
= 70
