Number of staplers that Jeremy had at first
= (203 - 41) ÷ 2
= 162 ÷ 2
= 81
Number of staplers that Glen had at first
= 81 + 41
= 122
Number of staplers that Jeremy sold in percent
= 100% - 30%
= 70%
70% =

122 - 10 u = 162 - 14 u
14 u - 10 u = 162 - 122
4 u = 40
1 u = 40 ÷ 4 = 10
Number of staplers that Glen had left
= 122 - 10 u
= 122 - 10 x 10
= 122 - 100
= 22
Answer(s): 22
