Say that you (or your parents) are purchasing a new car for $22,358. The sales tax is 6.45%, the down payment is 10% of the tota
Nastasia [14]

9514 1404 393

Answer:

  (a)  $133.88

Step-by-step explanation:

The addition of tax multiplies the purchase price by 1+6.45% = 1.0645. The payment of the down payment means the loan amount will be only 1-10% = 0.90 times the amount with tax. So, the loan amount is ...

  $22,359(1.0645)(0.90) = $21,420.08

The loan is a secured loan (secured by the vehicle). So, the interest charged is that for a poor credit rating: 7.5%.

One month's interest is ...

  I = Prt . . . . . interest on principal P at rate r for t years (1 mo = 1/12 yr)

  I = $21,420.08(0.075)(1/12) = $133.88
