Number of pens that Caden had before = 10 u
Number of pens that Caden gave to Peter = 1 u
Number of pens that Caden gave to Cody = 2 u
Number of pens that Caden gave to Jack = 2 u
Number of pens that Caden had left = 5 u
5 u = 30
1 u = 30 ÷ 5 = 6
Number of pens that Caden had at first
= 10 u
= 10 u x 6
= 60
