Johnny$$s Lunches is considering purchasing a new, energy$-$efficient grill. The grill will cost $$30,000$ and will be depreciated straight$-$line over $3$ years. It will be sold for scrap metal after $5$ years for $$7,500.$ The grill will have no effect on revenues but will save Johnny$$s $$15,000$ in energy expenses. The tax rate is $30\%.$
