Since i = 2% is the monthly rate, we multiply 2% x 12, the number of monthly periods in a year in order to determine the annual rate. In this case, Aaron needs to find an interest rate of 24% per year compounded monthly in order to reach his future value goal of $634 in one year.

Many types of toothpaste are. highly abrasive and actually strip away tooth enamel which never grows back. The teeth may become. sensitive when tooth enamel is worn away. Toothpasteâs abrasiveness is measure by its Relative Dentin. Abrasivity (RDA). The table below shows the RDA of some common toothpastes. We suggest that you. use toothpastes with lower RDA ratings. In addition to finding toothpaste that is minimally abrasive, we suggest finding one with fluoride. Fluoride helps strengthen enamel and prevent cavities.
