Suppose your friend loans you $200 for a week, which you agree to repay with 6% one-time interest. At the end of the week, how much money will you owe your friend? Summarize the information provided, stating the interest rate in a decimal form. Po = r = Identify the formula you will use to solve by writing the letter of the formula here: A. I = Por B. A = Po(1+r) C. A = Po(1 + rt) Solve the problem and give your answer here:

Assume the monthly payment of a loan amount of $400,000 is $1450. How long will it take to retire the loan if the annual interest rate is 4%? Using the equation  Monthly Payment + p x r/12 / 1-(1+r/12) ^-12y P = principal (the amount of your mortgage r = the annual interest rate y = length of the mortgage

Jonathan invested $1800 in a simple interest for 10 years. In the end, he received a final balance of $2520.00. Compute the interest amount Jonathan revived from the investment. R=  what was the rate of interest apr?

Substitute the given values into each given formula and solve for the unknown variable. If necessary, round to one decimal place.  I = PRT; I = 3750, P = 25,000, R = 0.05 (Simple interest formula)
