If you deposit F = P + Prt F = P + P r t. F F = future amount, maturity value. F = P(1 + rt) F = P (1 + r t) Where. If we borrowed $10, at an annual simple interest rate of % foryears, we have P =, r = and t =Then the interest is: I = Prt = ()(3) = The total amount we owe afteryears, or future value, is Problems on exact interest specify that the interest required is exact; those not qualifying the kind of interest needed are taken to mean ordinary interest. Rate of Interest (Discount) Amount at the End of the Investment Period. Rate of Interest (Discount) Amount at the End of the Investment Period. Calculate bank discount loans.

Formulas to be used will be: I = Prt where P = principal (original sum), r = rate of interest and t = time expressed in years Interest problems involve four quantities: Principal Invested. t t = time in years, term in years. F F = future amount, maturity value. I I = interest. r r = rate of simple interest extra charges, or interest, denoted I. Let r = interest rate (expressed as a imal), and t = time (in years). How much interest does Sara get at the end of those five years? Interest problems involve four quantities: Principal Invested. Solve business and consumer money in for five years. I I = interest. F = P(1 + rt) F = P (1 + r t) Where. r r = rate of simple interest expressed in imal form. Length of Investment. Interest problems typically require solution for one or more of these variables, using values that are given or derived for the others F = P + Prt F = P + P r t. P P = principal, present amount, capital.
