You can put this solution on YOUR website! A car salesman earns $18,000 a year, plus 8% of the amount of sales from the cars he sells. What is the minimum amount of sales he must make if he wants to earn at least $40,000 per year?
-----------
Let the minimum amt. be "x":
Inequality:
18000 + 0.08x >= 40000
0.08x >= 22000
x >= $275,000
