Calculator question...

"I have a question regarding the calculator we are allowed to use on the tests. Is the use of a Texas Instruments TI-83 graphing calculator permitted? Or must I go buy a financial calculator?"

I know that graphing calculators are very expensive, but you really need a (basic) financial calculator for this course and probably many other business courses (especially in finance and real estate). Now, I know a few higher-end graphing calculator models have a "time-value-of-money" menu, but the basic graphing calculators do not. Check your calculator carefully but you definitely need the TVM functions.
