4-An investor is about to make an investment of $45,000 in equipment that will bring a net annual income of $20,000. The equipment will last for only three years, has no resale value, and removal cost is negligible. An engineer suggests an improvement in the equipment that will cost $35,000 and will extend its life to six years but will not change the annual income. The equipment will have no resale value after the six-year life; the removal cost is again negligible. The investor has MARR of 10%. Use the rate of return method to make a recommendation to him. Explain your reasons for recommendation.

5- The following two proj ects are recommended for investment:

b. He can only put down $33M, and his bank will extend him a loan for the rest of the initial investment to be used on this project at 15% in a way that he has to pay it back in equal installments at the end of each of the five years with no collateral. Should he take the loan and invest? Yes? No? Why? Explain.
