Question

Jacob is renting an auger (used to drill holes for posts). On Home Depot's website, the charge is $65 plus $7 per hour. At Lowes, the charge is $95 plus $4 per hour. Determine when the costs would be the same.

Answer 1

10 hour rental

Explanation:

Let x = number of hours

HD cost: 7x + 65

L cost: 4x + 95

Set the two cost expressions equal and solve for x, the number of hours.

7x + 65 = 4x = 95

3x = 30

x = 10

The costs are equal for a 10 hour rental.
