WPP#6: Unit I Concepts 3-5- Compound Interest and Investment

Viewers need to be aware on what formula you use for the type of problem you are solving. The number correlating to the daily, weekly, monthly, etc. need to be memorized (which should be easy)! In the first problem, be aware that if you don't adjust your window accordingly, the tracing part won't work! (Trust me, I spent 20 minutes trying to figure out why it kept giving me ERROR!) In the second part, remember to find the ln to cancel out the e and continue on after that. Also, when you're looking for the time, remember to convert the rest of the decimal into months. (ex. 9.16 should convert to 9 months and 2 months (round to the next highest number for the months part))
