I have asked the same question four times and have been receiving incorrect answers. Please provide correct solution.

Assume it is January $2018$ and Johnny's Lunches is considering purchasing a new, energy$-$efficient grill. The grill will cost $$20,500$ and

will be depreciated in an asset class that carries a CCA rate of $30\%.$ It will be sold for scrap metal after $3$ years for $$4,900.$ The grill will

have no effect on revenues but will save Johnny's $$11,300$ in energy expenses. The firm has other assets in this asset class. The tax

rate is $35\%.$ Assume the discount rate is $11\%.$

b$.$ What are total cash flows in years $1$ to $3?($Do not round intermediate calculations. Round your answers to the nearest whole

dollar. Enter negative values with a minus sign.$)$
