Ave. Secured 5.85 Unsecured 6.75

OpenStudy (ineedatutor):

Anybody?

OpenStudy (retireed):

I might be wrong, but I can't solve this without knowing the length of the loan. How many months to pay off the loan? 36, 48 60 months?

OpenStudy (ineedatutor):

It doesn't say, but I do know that the answer to one is $25654.48

OpenStudy (ineedatutor):

the first question has two parts though.

OpenStudy (retireed):

Okay, I must be wrong about the length of the loan. But with the answer I might be able to figure it out. Hold on.

|dw:1463703586284:dw|

OpenStudy (ineedatutor):

371.41?

OpenStudy (retireed):

Opps! My mistake you did what I said but I forgot to add the cost of the car into my equation. Let me fix it.

OpenStudy (ineedatutor):

ok

OpenStudy (retireed):

|dw:1463704036872:dw|

OpenStudy (ineedatutor):

got you

OpenStudy (retireed):

Now you need to calculate the interest for the first month with the secured interest rate. 16353.59 * 0.0582/12 = __________ ?? I got $79.72 in interest cost

OpenStudy (ineedatutor):

I see

OpenStudy (ineedatutor):

What about number 2?

OpenStudy (retireed):

Do you understand how to do 1b ?

OpenStudy (ineedatutor):

I think I do.

OpenStudy (retireed):

Ok on to number 2|dw:1463704638164:dw|

OpenStudy (ineedatutor):

So

OpenStudy (ineedatutor):

167.63?

OpenStudy (ineedatutor):

That's what I got.

OpenStudy (retireed):

No let me see if I wrote it wrong again. I think I did it right.

OpenStudy (ineedatutor):

Ok

OpenStudy (retireed):

|dw:1463705179183:dw|

OpenStudy (ineedatutor):

I see

OpenStudy (ineedatutor):

I think I understand 2

OpenStudy (ineedatutor):

what about 3?

OpenStudy (retireed):

Three is just like 1b with different values and interest rates and calculating the difference in the first months interest. It is time for you to try again and show me your work and I will try to guide you through the steps.

OpenStudy (ineedatutor):

Alright.

OpenStudy (ineedatutor):

I got 87.55 for 3?

OpenStudy (retireed):

Calculate the total cost of the car... Cost + cost times sales tax - the down payment Take the total cost of the car (the principle) times the MONTHLY interest rate... Principle * IR/12 = first months interest Do this twice, once for the new car and once for the used car First months Interest New Car - First months interest Used car = _______ ?

OpenStudy (ineedatutor):

6817?

OpenStudy (retireed):

I got a little less than half of your value. You could be correct, but I can't tell where my mistake is if you don't show your work.

OpenStudy (ineedatutor):

Oh ok. i'll just show my work.

OpenStudy (retireed):

What is the 6817 answer for?

OpenStudy (ineedatutor):

When you said "First months Interest New Car - First months interest Used car = _______" I just subtracted the price of the new car from the old car

OpenStudy (ineedatutor):

$19,242.00-$12,425.00=6817

OpenStudy (retireed):

No that is just the difference in the total value of the cars.

OpenStudy (ineedatutor):

I see

OpenStudy (ineedatutor):

Alright, I think I see how to get this

OpenStudy (retireed):

ok bye

OpenStudy (ineedatutor):

Thanks for your help.

OpenStudy (ineedatutor):
