A construction company can purchase a used backhoe for $90,000 and spend $450 per day in operating costs. The equipment will have a 5-year life with no salvage value. Alternatively, the com­pany can lease the equipment for $800 per day. How many days per year must the company use the equipment in order to justify its purchase at an in­terest rate of 8% per year.

What will be an ideal response?


90,000(A/P,8%,5) + 450x = 800x
90,000(0.25046) + 450x = 800x
x = 64.4 days
