Question

Frank wants to buy an entertainment system that costs $500, including taxes. To pay for the entertainment system, he will use a payment plan that requires him to take a down payment of $125, and then pay $72.50 each month for 6 months. What is the percent increase from the original cost of the entertainment system to the cost of the entertainment system using the payment plan?

Answer 1

Answer: The percent increase from the original cost of the entertainment system to the cost of the entertainment system using the payment plan is 12%.

Explanation:

Hi, to answer this question, first we have to obtain the price paid using the payment plan:

• Downpayment: $125
• $72.50 each month for 6 months: 72.50 x 6 = 435

Cost using payment plan: 125+435=560

Original cost: $500

If we compare the price by applying the formula:

Percentage increase = (higher value - lower value/ lower value) \times 100

Replacing with our values:

P = ( 560-500/500)x100 = 0.12 x 100 =12%

Feel free to ask for more if needed or if you did not understand something.

Answer 2

The answer is $66.

72.50•6=$441
441+125=$566
566-500=$66
