Required
Determine the inequality
First, we need to determine the total cost for x miles.



The total cost can not exceed the amount he has, so the inequality is:

24 pens divided by 2 boxes equals 12 pens per box.
The first one is (z-7)(z-1)
second: (x+1/3)(x+1/3)
third: (x-1/5)(x-1/5)
fourth: (x-5)(x-2)
He just switched sides of the variables and numbers. Instead if adding the opposite.
