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 week40

 40*300=$12000it 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 

it is part of the rising action that reveals public sentiment toward hester.
