Number of staplers that Caden had at first
= (74 - 14) ÷ 2
= 60 ÷ 2
= 30
Number of staplers that Sean had at first
= 30 + 14
= 44
Number of staplers that Caden sold in percent
= 100% - 30%
= 70%
70% =

(1) = (3)
44 - 10 u = 60 - 14 u
14 u - 10 u = 60 - 44
4 u = 16
1 u = 16 ÷ 4 = 4
Number of staplers that Sean had left
= 44 - 10 u
= 44 - 10 x 4
= 44 - 40
= 4
Answer(s): 4
