Our topic was percents and proportions.
Percents andproportions are used for commisions rates, unit rates, converting currency, and simple interest. In our video we used simple interest, for a person buying a car and needing to find how much money they will need when they take out a loan to buy the car. We used the simple interest formula because the car had 5% intrest for 5 years. We used I=PRT to find the interest I=PRT is principle times rate times time. Simple interest is one of the easiest equations for percent and proportions.
