jim766 · Answer

if the number of cars is C  and his Salary is at least  >=

 27,200 + 320C >= 56,000      solve for C

Fixed + Commission
$27200 + 320x       (x=number of cars sold)

27200 + 320x = 56000
              320x = 28800
                    x = 28800/320
                   x = 90

the question says at least......he would have to sell 90 cars to make exactly 56,000
but he sold more cars he would make more.

$$x \ge90$$

read the question carefully it says minimum cars sold to make 56000, the minimum is just 90 cars to be right on $56000.
