- Depreciation Once a new car is driven away from the dealer, it begins to lose value. Each year, a car loses 10% of its value. This means that each year the value of a car is 90% of the previous year’s value. If a new car was purchased for $20,000, the value at the end of the first year would be $20000(0.90) and the value of the car after the end of the second year would be $20000(0.90)2. Complete the table shown below. What will be the value of the car at the end of the eighth year? Simplify the expression, to show the value in dollars.arrow_forwardFuture Value In certain savings scenarios, the value F of an investment after t years, the future value, is given by F=P1+rt. Here r is the yearly interest rate as a decimal, P is the amount of the original investment and t is the term of the investment. If we invest 1000 at an interest rate of 0.06 per year as a decimal, and if the term of the investment is 5 years, what is the future value?continuedarrow_forwardThe Truth in Lending Act Many lending agencies compound interest more often than yearly, and, as we noted in Example P.2, they are required to report the annual percentage rate, or APR, in a prominent place on the loan agreement. Furthermore, they are required to calculate the APR in a specific way. If r is the monthly interest rate, then APR is calculated using APR=12r. a. Suppose a credit card company charges a monthly interest rate of 1.9%. What APR must the company report? b. The phrase annual percentage rate leads some people to believe that if you barrow 6000 from a credit card company that quotes an APR of 22.8%, and if no payments are made, then at the end of 1 year, the interest would be calculated as 22.8% simple interest on 6000. How much would you owe at the end of a year if interest is calculated in this way? c. If Interest is calculated monthly which is common, then the actual amount you would owe in the situation of part b is given by 60001.01912. What is the actual amount you would owe at the end of a year?arrow_forward
- Heart Disease In a certain country, the number of deaths due to heart disease decreased from 235 in one year to 221 in the next year. What percentage decrease in deaths due to heart disease does this represent?arrow_forwardAn Amortization Table Suppose you borrow P dollars at a monthly interest rate of r as a decimal and wish to pay off the loan in t months. Then your monthly payment can be calculated using M=Pr(1+r)t(1+r)t1 dollars. Remember that for monthly compounding, you get the monthly rate by dividing the APR by 12. Suppose you borrow 3500 at a 9 APR meaning that you use r = 0.09/12 in the preceding formula and pay it back in 2 years. a. What is your monthly payment? b. Lets look ahead to the time when the loan is paid off. i. What is the total amount you paid to the bank? ii. How much of that was interest? c. The amount B that you still owe the bank after making k monthly payments can be calculated using the variables r, P, and t. The relationship is given by B=P((1+r)t(1+r)k(1+r)t1) dollars. i. How much do you still owe the bank after 1 year of payments? ii. An amortization table is a table that shows how much you still owe the bank after each payment. Make an amortization table for this loan.arrow_forwardRound each percentage increase or decrease that you calculate to the nearest tenth of a percent.
