Step-by-step explanation:

A road building contractor has received a major highway construction contract that will require 50,000 m3 of crushed stone each year for 5 years. The stone can be obtained from a quarry for $7.80/m. As an alternative, the contractor has decided to try to buy the quarry. He believes that if he owned the quarry, the stone would cost him only $6.30/m3. He thinks he could resell the quarry at the end of 5 years for $200,000
