Investments and loans base their interest calculations on one of two possible methods: the interest and the interest methods. Both methods apply three variables-the amount of principal, the interest rate, and the investment or deposit period-to the amount deposited or invested in order to compute the amount of interest. However, the two methods differ in their relationship between the variables. Assume that the variables I, N, and PV represent the interest rate, investment or deposit period, and present value of the amount deposited or invested, respectively. Which equation best represents the calculation of a future value (FV) using: Compound interest? FV=(1+I)N/PVFV=PV(1+I)NFV=PV+(PVIN) Simple interest? FV=PVINFV=PV(PVIN)FV=PV+(PVIN) Identify whether the following statements about the simple and compound interest methods are true or false. The process for converting present values into future values is called . This process requires knowledge of the values of three of four time-value-of-money variables. Which of the following is not one of these variables? The duration of the investment (N) The interest rate (I) that could be earned by invested funds The inflation rate indicating the change in average prices The present value (PV) of the amount invested All other things being equal, the numerical difference between a present and a future value corresponds to the amount of interest earned during the deposit or investment period. Each line on the following graph corresponds to an interest rate: 0%, 10\%, or 20%. Identify the interest rate that corresponds with each line. Line A: Line B: Line C
