A company borrows \( \$ 10,300 \) from the bank at \( 15 \% \) interest for thirty days. \( \$ 10,300 \) is the maturity value of the note is the nearest dollar.) A. mor computation of interest, use a 365 -day year. (Round your final answer to B. principal; \( \$ 10,427 \) C. present value; \( \$ 10,300 \) D. future value; \( \$ 10,300 \)

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.

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 \( \$ \)

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.)

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

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.)
