Thornton Freight Company owns a truck that cost $$42,000.$ Currently, the truck's book value is $$26,000,$ and its expected remaining useful life is five years. Thornton has the opportunity to purchase for $$28,000$ a replacement truck that is extremely fuel efficient. Fuel cost for the old truck is expected to be $$6,700$ per year more than fuel cost for the new truck. The old truck is paid for but, in spite of being in good condition, can be sold for only $$17,000.$
