A retired couple buys a new recreational vehicle (RV) for $42,000.00. They make a down payment of $13,000.00 and finance the balance at 9.0% APR over 60 months.
Their monthly payment is $601.99.
Before making the 12th payment, the couple decides to pay the remaining balance on the loan.
Use the actuarial method to determine how much interest the couple will save.

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.

the area of the rectangle is 35units^2.

step-by-step explanation:

graph it and find the distance.

it is a 5*7 rectangle.

therefore the area is 35units^2.

5 + 8 +7 + 4 + 0 +1 = 25
