Lisa Peck, the owner of Coastal Photography, is considering purchasing a drone for use in taking aerial photos. The drone would cost $$10,000$ and have a four$-$year useful life with a $$2,000$ salvage value. Buying the drone would allow Lisa to develop a new line of photos that she could sell to companies for use in their advertisements. Lisa estimates that the contribution margin per year from the new line of photos would be $$3,000.$
