When you buy a certificate of deposit (CD), you are investing your money in an account that earns interest for a specific period of time. A CD matures when it has been invested for the required amount of time. Assume that you have $3300 to invest in a 3-year CD with an APR of 3.5% compounded daily. When the CD matures, how much interest will you have earned? Round your result to the nearest cent

your credit card has a balance of $4,500 and an annual interest rate of 16%. you decide to pay off the balance over 3 years. if there are no further purchases charged to the card, a.- how much must you pay each month? b.-what is the total interest paid over 3 years?

You expect to have the given amount in an account with the given terms. Find how much you can withdraw periodically in order to make the account last the specified amount of time. Round your answer to the nearest cent. Account balance: $700,000 Interest rate: 4.65% monthly 17 years Frequency Time: Periodic Withdraw: $

Suppose you deposit m dollars the beginning of every month in a savings account that earns a monthly interest rate of r. For an initial investment of m dollars, the amount of money in your account at the beginning of the second month is the sum of your second deposit and your initial deposit plus interest. Denote by An the amount of money in your account in the nth month. 1. Explain why A₁ = m dollars. 2. Explain why A₂ = m+m(1+r) dollars. 3. Write down explicit expressions for A3 and A4. This is the crucial step. 4. Explain why An = m+m(1 + r) + m(1 + r)² + ... +m(1 + r)"−¹ dollars. 5. Use the formula for a geometric sum to show that An = m (1 + r)” − 1 r dollars. 6. If your account has a monthly interest rate r = 0.002 and you deposit $200 monthly for 5 years, how much money will you have in your account after the 5 years? (Hint: How many months?)
