The Elberta Fruit Farm of Ontario is considering buying a cherry$-$picking machine to replace the part$-$time workers it usually hires to harvest its annual cherry crop. The machine shakes the cherry tree, causing the cherries to fall onto plastic tarps that funnel the cherries into bins. The company gathered the following information:

a$.$ The farm pays part$-$time workers $$200,000$ per year to pick the cherries.

b$.$ The cherry picker would cost $$480,000,$ have a $8-$year useful life with no salvage value, and be depreciated using the straight$-$line method.

c$.$ The cherry picker's annual out$-$of$-$pocket costs would be cost of an operator and an assistant, $$94,000$; insurance, $$3,000$; fuel, $$11,000$; and a maintenance contract, $$14,000.$
