Tank Ltd is considering undertaking the purchase of a new piece of equipment that is expected to increase revenue by $12,000 each year for six years. The equipment will increase costs $4,000 each year for six years. It costs $32,000 to purchase today and for tax purposes must be depreciated down to zero over its 8 year useful life using the straight-line method. If Tank is actually forecasting a salvage (for capital budgeting purposes) of $5,000 after 6 years, what is the machine's net cash flow (after tax) for year 6? Assume the tax rate is 30%.

A. 13,000B. 11,800C. 12,700D. 12,400

Would someone please be able to help me with this multiple choice question? I don't understand how to do it. Thank you
