I need answer to this question,do not copy paste from Chegg.

Trader Bubba Industries must choose between solar and an electric-powered forklift truck for moving materials in its factory. Because both forklifts perform the same function, the firm will choose only one. (They are mutually exclusive investments.) The solar truck will cost more, but it will be less expensive to operate; it will cost $30,000, whereas the electric-powered truck will cost $20,000. The life for both types of truck is estimated to be 6 years, during which time the net cash flows for the solar-powered truck will be $8,000 per year and those for the electric-powered truck will be $5,000 per year. Trader Bubba Industries assets are $750 million, financed through bank loans, bonds, preferred stocks, and common stocks. The amounts are as follows: Bank loans: $ 100 million borrowed at 3% Bonds: $280 million, paying 5% coupon with semi-annual payments, and maturity of 10 years.
