A choice needs to be made between the two alternatives stated, make a recommendation as to what interest rate is to be used. Graph the PW of each altemative vs Interest rate. i) Write the equations for PW Atematve A and PWAltematre B (2 marks) ii) Substitute the range of i (5,10,15,20,25%) into the PW equations for the two alternatives. iii) Draw the graph for PW vs Interest rate for the points generated in part (ii) for the two altematives on one graph. iv) Calculate the rates for the two alternatives on Exeel. v) What interest rate and Alternative should be chosen? Please submit the PW vs Interest rate graphs for the two alternatives as well as the spreadsheet showing interest rate calculations. (5marks)
