Explanation:

Data:

Mortgage: $95,000; Years: 30; Interest Rate: 6%.

a. Find the monthly payment using the table above.

Locate the cell at the intersection of the column for 30 length of loan in years,  and the row for 6.00% interest.

The cell has value 6.00

That is the monthly payment for a loan of $1,000.

For a mortage of $95,000 divide by 1,000 and multiply by the value of the corresponding cell, 6.00 in this case.

$95,000/1,000 × 6.00 = $570

Thus, the monthly payment is $570.

b. Find the total amount paid.

You need to multiply the montly payment by the number of months in 30 years.

Number months = 12 × 30 = 360Total amount paid = number of months × montly payment = 360months × $570/month = $205,200

Hence, the total amount paid is $205,200.

c. Find the total interest paid.

The total interest paid is the difference between the total amount paid and tha amount of the loan (mortgage).

Total interest = total amount paid - loan amountTotal interest = $205,200 - $95,000 = $110,200

Therefore, the total interest pais is $110,200,

d. Find the monthly payment to the nearest cent using the formula above. Do not round until your final answer.

The formula for the factor is:

             

Where,

n is the number of periods; months in this case = 360, andi is the interest of one period: 6%/12 = 0.06/12 = 0.005

Substitute and compute:

That factor is for $1.00

Multiply by $95,000:

Payment = $95,000 × 0.00059955 = $569.57

Therefore, the monthly payment to the nearest cent using the formula is $569.57

e. What is the difference (in dollars) in interest if you use the formula versus the table?

Total amount paid = number of payments × monthly paymentTotal amount paid = 360 months × $569.57/month = $205,045.20Total interest = total amount paid - amout of the loan$205,045.20 - $95,000 = $110,045.20Difference: $110,200 - $110,045.20 = $154.80

Hence, the difference in interest if you use the formula versus the table is $154.80
