\( 500.000 .000 = \$ 50.000 .000 \cdot ( 1 + 0.25 ) ^ { n } \)

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

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.)

25. You own a custom computer software business. You must invest \( \$ 3,255 \) for computer hardware, and spend \( \$ 2.90 \) to buy and package each disk. If each disk sells for \( \$ 13.75 \), write a system of equations and determine how many disks you must sell to break even. 26. The ballpark needs to make at least \( \$ 15,000 \) from ticket sales. The ticket prices are \( \$ 20 \) for

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 \( \square \% \).

Determine the present value \( P \) that must be invested to have the future value \( A \) at simple interest rate \( r \) after time \( t \). \[ A=\$ 5000, r=2.5 \%, t=6 \text { years } \] The present value \( P \) that must be invested is \( \$ \) (Round up to the nearest cent.)
