The principal \( P \) is borrowed at a simple interest rate \( r \) for a period of time \( t \). Find the simple interest owed for the use of the money. Assume 365 days in a year. \( P=\$ 7000, r=4.5 \%, t=18 \) months The simple interest owed for the use of the money is \( \$ \square \). (Do not round until the final answer. Then round to the nearest cent as needed.)

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.)

You deposit \( \$ 13,000 \) in an account that pays \( 1.51 \% \) interest compounded quarterly. a. Find the future value after one year. b. Use the future value formula for simple interest to determine the effective annual yield. i. Click the icon to view some finance formulas. a. The future value is \( \$ \square \). (Round to the nearest cent as needed.) b. The effective annual yield is \( \square \% \). (Round to the nearest hundredth as needed.)

Advice from most financial advisers states to spend no more than \( 28 \% \) of one's gross monthly income for one's mortgage payment, and to spend no more than \( 36 \% \) of one's gross monthly income for one's total monthly debt. Suppose a family has a gross annual income of \( \$ 43,200 \). a. What is the maximum amount the family should spend each month on a mortgage payment? b. What is the maximum amount the family should spend each month for total credit obligations? c. If the family's monthly mortgage payment is \( 80 \% \) of the maximum they can afford, what is the maximum amount they should spend each month for all other debt? a. The maximum monthly mortgage payment should be \( \$ \square \). b. The maximum monthly total credit obligations should be \( \$ \square \). The maximum amount they should spend monthly on all other debt is \( \$ \)

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
