You can buy a computer with your credit card and pay for it over the course of one year. With an interest rate of 16 percent, you would need to pay $181.46 for 12 months to pay off the charge. You can rent the computer for 12 months for $200 per month and, at the end of the rent period, buy it for $300. How much will you save by purchasing the computer with your credit card instead of using the rent-to-own plan?
