\( \frac{7000 / 3500}{1+3.5 / 100} \frac{0.3019}{0.0350} \) c. Find the time it takes for your investment to triple in the compound interest model when the interest rate is \( 3 \% \).

The principal \( P \) is borrowed at simple interest rate \( r \) for a period of time \( t \). Find the loan's future value, \( A \), or the total amount due at time \( t \). \( P=\$ 38,000, r=6.5 \%, t=5 \) years The future value is \( \$ \square \). (Simplify your answer. Type an integer or a decimal.)

To borrow money, you pawn your guitar. Based on the value of the guitar, the pawnbroker loans you \( \$ 1080 \). One month later, you get the guitar back by paying the pawnbroker \( \$ 1272 \). What annual interest rate did you pay? You will pay a simple interest rate of \( \square \% \) (Round to the nearest whole number as needed.)

Determine the effective annual yield for each investment. Then select the better investment. \( 3.06 \% \) compounded monthly; \( 3.07 \% \) compounded annually Click the icon to view some finance formulas. Select the correct choice below and fill in the answer boxes within your choice. (Round to the nearest hundredth as needed.) A. The second investment, \( 3.07 \% \) compounded annually, is the better investment because the effective annual yield for the first investment is investment is \( \square \% \). The first investment, \( 3.06 \% \) compounded monthly, is the better investment because the effective annual yield for the first investment is \( \square \% \) annual yield for the second investment is \( \square \% \).

For the investment situation below, identify the annual interest rate, the length of the investment in years, the periodic interest rate, and the number of periods of the investment. \( 9 \% \) compounded monthly for 3 years (a) the annual interest rate (b) the length of the investment in years (c) the periodic interest rate (d) the number of periods of the investment

Suppose that you camed a bachelor's degree and now youre teaching high school. The school district offers teachers the opportunity to take a year off to eam a master's degree. To achieve this goal, you deposit \( \$ 1000 \) at the end of each year in an annuity that pays \( 5.5 \% \) compounded annually. a. How much will you have saved at the end of five years? b. Find the interest.
