d) 2n+5
This is because you know how many packages of 5 pens he bought which is 1. So that stays the same. you are trying to figure out how many packages of 2 pens he bought so that is a variable. so to find the total number of pens it is 2n+5.

5*1 = 5 [He bought one package containing 5 pens]
n*2 = 2n [and n packages containing two pens each]

So the total number of pens that he bought is 2n+5
