select the correct answer. adam bought a treadmill and a dirt bike from a sports equipment store for y dollars. he signed an installment agreement requiring an 8% down payment and monthly payments of x dollars for 18 months. which expression correctly represents adams finance charge? a. 0.8y b. 18y c. 18x - 0.92y d. 18x - 0.08y e. 18y - 0.92x
Answer
Explanation:
Step1: Calculate the down - payment amount
The down - payment is 8% of the total cost $y$. So the down - payment amount is $0.08y$.
Step2: Calculate the amount financed
The amount financed is the total cost minus the down - payment. So it is $y - 0.08y=0.92y$.
Step3: Calculate the total amount paid in installments
The monthly payment is $x$ dollars for 18 months. So the total amount paid in installments is $18x$.
Step4: Calculate the finance charge
The finance charge is the total amount paid in installments minus the amount financed. So it is $18x−0.92y$.
Answer:
C. $18x - 0.92y$
