Find [tex]\( c \)[/tex], the total of the payments, and the monthly payment. Choose the correct answers.

[tex]\[ \operatorname{Interest}(I) = \frac{2 y c}{m(n+1)} \][/tex]

Joe Summers buys a gas grill and accessories. The cost, including tax, amounts to [tex]\(\$850.00\)[/tex]. Joe finances the grill over 12 months after making a [tex]\(\$150\)[/tex] down payment. The true annual interest rate is [tex]\(14\%\)[/tex]. What are Joe's monthly payments (principal plus interest)?

To the nearest penny, [tex]\( c = \$ \square \)[/tex]

Total of payments [tex]\( = \text{amount} \square + c = \$ \square \)[/tex]

[tex]\[
\frac{\text{Total of payments}}{\text{number of payments}} = \text{monthly payment} = \$ \square
\][/tex]

Options:
A. 55.67
B. 58.15
C. 53.08



Answer :

To solve this problem, we must determine both the total of the payments (denoted as [tex]\( c \)[/tex]) and the monthly payment Joe needs to make for financing his gas grill purchase. Here are the step-by-step calculations:

1. Determine the Principal (Amount Financed):

The total cost of the gas grill and accessories is [tex]$850.00. Joe makes a down payment of $[/tex]150.00. This means the amount financed (principal) can be calculated as follows:
[tex]\[ \text{Principal} = \$850.00 - \$150.00 = \$700.00 \][/tex]

2. Calculate the Interest ([tex]\( I \)[/tex]):

According to the formula:
[tex]\[ \text{Interest}(I) = \frac{2yc}{m(n+1)} \][/tex]
Given values:
- True annual interest rate, [tex]\( y = 0.14 \)[/tex] (14%)
- Total principal amount, [tex]\( c = \$700.00 \)[/tex]
- Number of months, [tex]\( n = 12 \)[/tex]

Plugging in the values:
[tex]\[ I = \frac{2 \times 0.14 \times 700}{12 \times (12 + 1)} \][/tex]

After performing the calculation of interest, we get:
[tex]\[ I \approx \$1.26 \][/tex]

3. Calculate the Total of Payments ([tex]\( c \)[/tex]):

The total of payments is the sum of the principal and the interest:
[tex]\[ c = \$700.00 + \$1.26 = \$701.26 \][/tex]

4. Determine the Monthly Payment:

The total of the payments is divided by the number of months to find the monthly payment:
[tex]\[ \text{Monthly Payment} = \frac{\$701.26}{12} \approx \$58.44 \][/tex]

Thus, the detailed incidentals are:
- To the nearest penny, [tex]\( c = \$701.26 \)[/tex]
- Total of payments = [tex]\( \$701.26 \)[/tex]
- Monthly payment = \[tex]$58.44 The correct answer choices are: - \( c = \$[/tex]701.26 \)
- Total of payments = amount [tex]$+ c = \$[/tex]701.26 \)
- Monthly payment = \$58.44
