4. Interest may be calculated more often than once per year. The process is the same, and the interest rate r is still expressed as an annual interest rate, but you will only receive a portion of annual interest each time period. For example, if we invest $1800 at an annual interest rate of 2.40% compounded quarterly, how much will our investment be worth after two years? Below is a chart. Note that in the interest calculation for the first quarter of the year, we do not receive (1800)(0.024)=43.20. Fhstead, we receive one quarter of that amount since the annual interest needs to be divided into four payments. However, after the first quarter, we will be earning interest on the interest, so that after one year, we will have earned more than $43.20 in interest. The interest for the first quarter should be (1800)(0.024)(41)=10.80. Write an expression for the value of the investment A after two years, beginning with an initial value of P, invested at an interest rate of r, compounded n=4 times per year. 4.
