The price of a new car is \$16,000. Assume that an individual makes a down payment of 25% toward the purchase of the car and secures financing for the balance at the rate of 6%/year compounded monthly. (Round your answers to the nearest cent.)

What monthly payment will she be required to make if the car is financed over a period of 48 mo? Over a period of 72 mo?

What will the interest charges be if she elects the 48-mo plan? The 72-mo plan?

• finite math -

\$12,000 loan amount
r = .06/12 = .005
n = 48 or 72
1+r = 1.005
(1+r)^-n = .7871 for n = 48
1 - (1+r)^-n = .2129 for n = 48
payment = loan [ r/(1 -(1+r)^-n ) ]
payment for 48 months = 12,000[.005/.2129]
=\$281.82
now you do the 72 months

i got \$198.87

LOL
well
12,000/48 = 250 per month with no interest.
you paid 281.82 including the interest at 6% compounded monthly

• finite math -

(281.82-250)*48?

right

Determine the simple interest rate at which will grow to in the months. Round your answer to the nearest tenth of percent
