Number of staplers that Tim had at first
= (96 - 4) ÷ 2
= 92 ÷ 2
= 46
Number of staplers that Cody had at first
= 46 + 4
= 50
Number of staplers that Tim sold in percent
= 100% + 25%
= 125%
125% =

(1) = (3)
50 - 4 u = 92 - 10 u
10 u - 4 u = 92 - 50
6 u = 42
1 u = 42 ÷ 6 = 7
Number of staplers that Tim had left
= 46 - 5 u
= 46 - 5 x 7
= 46 - 35
= 11
Answer(s): 11
