EXPONENTIAL FUNCTIONS Compound Interest (Page 1 of 5)

One application of exponential functions are the compound interest formulas. Let's use the SOLVER to work with some problems involving the formula A = P(1+r/n)^(n*t). To use the SOLVER, first write this formula as an equation set equal to zero: A-P(1+r/n)^(n*t) = 0. Then access the SOLVER, which is located in the MATH MATH submenu.

 MATH key. Up arrow key. 0: menu selection. Calculator screen image.

If your equation line is not blank (following the equal sign), press CLEAR key.. If you do not see this screen at all, press Up arrow key.. Click here if there is an equation already entered that you need to clear.
