An excavating company charges $300 an hour for the use of a backhoe and $500 an hour for the use of a bulldozer. (part of an hour counts as a full hour. ) The company employs one operator for 40 hours per week to operate the machinery. If the company wants to bring in at least $18,400 each week from equipment rental, how many hours per week can it schedule the operator to use a backhoe?

We have that

Cost use of a backhoe----------------------$300 an hour

 Estimate for equipment rental each week---------------------$18,400

Total hours operator per week--------------------------------------40

 40*300=$12000---------------------it is the cost per week to use a backhoe

 $12000<$18400  is ok 

 The maximum of hours that I can rent a backhoe  are 40 hours, since it is the limit of the operator and it do not overcome the total budget
