(a)
Answer to Problem 22P
From table below, from 0% to 4.7%, Alternative C should be preferred. Between 4.7% to 6.9%; Alternative B should be preferred. Alternative A should be preferred for interest rate between 6.9% to 8.2%.

- Two receipts of $1,000 each are desired at the EOYs 10 and 11. To make these receipts possible, four EOY annuity amounts will be deposited in a bank at EOYs 2, 3, 4, and 5. The bank’s interest rate (i) is 12% per year. (a) Draw a cash-flow diagram for this situation. (b) Determine the value of A that establishes equivalence in your cash-flow diagram. (c) Determine the lump-sum value at the end of year 11 of the completed cash-flow diagram based on your answers to Parts (a) and (b).arrow_forwardEngineering Economics Please provide a step by step solution using present worth methodarrow_forwardThe surface are of a certain plant that requires painting is 8,000 sq. ft. Two kinds of paint are available whose brands are A and B. Paint A costs P1.40 per sq. ft. but needs renewal at the end of every 4 years, while paint B costs P1.80 per sq. ft. If money is worth 12% effective, how often should paint B be renewed so that it will be as economical as Paint A?arrow_forward
