The store offered a payment plan consisting of a $20 down payment and 12 monthly payments of $10,
the total payment made for the purchase is\(20 + 12 * 10 = 20 + 120 = 140$\)

Therefore he would have paid \(140 - 120 or 20\)$ in interest

Since, we need to find what percent of the purchase price did the customer pay in interest,
it must be \(\frac{20}{120} * 100 = \frac{1}{6} * 100 = 16.7\)%(Option A)

On a purchase of $120, a store offered a payment plan consisting of a $20 down payment and 12 monthly payments of $10 each. what percent of the purchase price, to the nearest tenth of a percent, did the customer pay in interest by using this plan?

A. 16.7%
B. 30%
C. 75.8%
D. 106.7%
E. 107.5%
Subtract the down payment. Find the difference between original amount owed and final amount paid. That's interest. Finally, find percentage required.

Purchase price = $120

Less the $20 down payment =
120 - 20 = $100 to pay off at beginning

Payment total at end is $10/month * 12 months = $120

She had $100 to pay at beginning. She paid $120 by the end.

The difference is interest: $120 - 100 = $20 in interest

$20 is what percent of purchase price $120?

\(\frac{20}{120}\) = \(\frac{1}{6}\) * 100 = 16.66... = 16.7%

Answer A

A. 16.7%

E. 107.5%

Price of item = 120 $
Total cost to customer = 20$ + 10$*12 = 140$
Interest paid over 12 monthly payments = 20$
Percentage interest = 20/120 * 100%
= 16.67%

A. 16.7%
B. 30%
C. 75.8%
D. 106.7%
E. 107.5%

When the customer used the payment plan, he or she paid 20 + 10 x 12 = 140 dollars, which is 20 dollars more than the purchase price. That is, the interest is 20 dollars using the payment plan.

Thus, the interest paid is 20/120 = 1/6 = 16.7%.

­The term "nearest tenth of a percent" means rounding a percentage to one decimal place. For example, if you have a percentage like 5.67%, rounding it to the nearest tenth of a percent would give you 5.7%. Similarly, if you have 3.42%, it would round to 3.4%.
