Like many college students, Miriam applied for and got a credit card that has an annual percentage rate (APR) of 12%. The first thing she did was buy a new DVD player for $250. At the end of the month, her credit card statement said she only needed to make a minimum monthly payment of $15. Assume Miriam makes her payment when she sees her statement at the end of each month. If Miriam doesn't charge any additional amounts, and the credit card company compounds interest at the end of each month, how long will it take her to pay off the DVD player?

A. 20.8 months
B. 40.2 months
C. 32.6 months
D. 19.3 months
E. 18.3 months

Miriam now realizes she needs to pay more than just the minimum payment (unless she wants to be paying for the DVD player for a long time). She decides to pay twice the minimum monthly payment ($30 per month) instead. How much quicker will she pay off the DVD player?

A. 23.1 months
B. 13.9 months
C. 9.6 months
D. 17.9 months

Answer :

Miriam will be able to pay off the DVD player in approximately 13.9 months, which is significantly quicker than making just the minimum payments.

Initially, Miriam bought a DVD player for $250 using her credit card with an APR of 12%. The credit card statement indicated that she only needed to make a minimum monthly payment of $15.

To determine how long it would take for Miriam to pay off the DVD player if she only made the minimum payments, we can use the formula for the number of months to pay off a debt:

N = -(log(1 - (B/M) * (1 + r)) / log(1 + r))

Where:

N is the number of months to pay off the debt,

B is the initial balance ($250),

M is the monthly payment ($15),

and r is the monthly interest rate (APR divided by 12, so 12%/12 = 1%).

Plugging in the values:

N = -(log(1 - (250/15) * (1 + 0.01)) / log(1 + 0.01))

N ≈ 32.6 months

Therefore, it would take Miriam approximately 32.6 months to pay off the DVD player if she only made the minimum monthly payments.

If Miriam decides to pay twice the minimum monthly payment ($30 per month), we can calculate the new time to pay off the debt using the same formula:

N = -(log(1 - (250/30) * (1 + 0.01)) / log(1 + 0.01))

N ≈ 13.9 months

By paying twice the minimum monthly payment, Miriam will be able to pay off the DVD player in approximately 13.9 months, which is significantly quicker than making just the minimum payments.

Therefore, paying more than the minimum payment each month will significantly reduce the time it takes for Miriam to pay off the DVD player.
