I need help solving letter c (I have already solved the previous problems a and b shown below):

Kenny and Jannah qualify for a 6-year car loan with a 10.1% APR and a 3-year car loan with an 8.5% APR. They found a new 2019 Ford F250 Superduty listed at $39,900. Their combined monthly income is $6100 during ski season, but they know that will drop in the summer. They know they shouldn't pay more than 10% of their income on car payments.

a) Assuming Kenny and Jannah make the down payment from part (a) and will make payments for the entire life of the loan, how much will they pay monthly for each loan option? Are either of these options within 10% of their monthly income? Indicate which formula you use and identify all of the relevant variables (A, P, APR, n, Y, and/or PMT).

Loan Option 1 (6 years):Loan Option 2 (3 years):

A= $671.88948711.01%A= $976.919748918.71%

Neither of these options are within 10% of their monthly income.

b) Assuming Kenny and Jannah will make payments for the entire life of the loan, how much will they pay in total for the F250 with each loan option?

Pay in total for option 1:Pay in total for option 2:

A= $52106.87671A= $44834.60815

Kenny has been competing in Ski Ballet, and recently won the national championships. Now, he wants to use the prize money ($5000) to make a larger down payment.

c) If Kenny and Jannah decide to put the prize money toward their down payment, how will this affect the amount they would pay each month for each loan option (i.e. how much money would it save them each month for each option)? Indicate which formula you use and identify all of the relevant variables (A, P, APR, n, Y, and/or PMT).
