Answer parts a, b, c, and d based upon the two design alternatives shown in the table below. Assume an interest rate of 6%: 1. Initial Cost Annual Revenue Useful Life Alternative A $10,000 $5,000 3 years Alternative B $15,000 $4,000 in odd years & $7,000 in even years 4 vears a. Draw the cash flow diagram representing 1 useful life for each alternative (A and B) b. Show the calculations to determine the Annual Worth (AW) of 1 useful life for each alternative (A and B). Also provide the calculated values for AW below AWA, 1 useful life (EUAWA)- AWB, 1 useful life (EUAWB)- Draw the cash flow diagram for each alternative (A and B) that shows repeatability across a 12 year study period. c. d. Show the calculations to determine the Annual Worth (AW) of each alternative. Also provide the calculated values for AW below AWA, 12 year study period (EUAWA)- AWB, 12 year study period (EUAWB)
