Each expression below will convert a specific cash flow or cash flow series into a present value. Draw the cash flow diagram that is represented by the expression. Example: 10(P/F, r, 5) = a. 100(P/A, r, 10) b. 50(P/F, r, 5) + 100(P/A, r, 10) c. 100(P/F, r, 3) + 200(P/F, r, 6) d. 1,000(P/A, r, 5) + 250(P/G, r, 5)
