Answer:
The monthly payment will be $434
Explanation:
Price of New car = $21,900
Price of old car exchanged = $2,350
Cash Payment = $850
Amount of Loan = $21,900 - $2,350 - $850
Amount of Loan = A = $18,700
Rate of interest = r = 6% = 0.06 = 0.005 per month
Number of total periods = 12 x 4 = 48
P = $18500 / { [ ( 1 + 0.005 )^48 ] - 1 } / [ 0.005 ( 1 + 0.005)^48 ]
P = $18500 / [ 0.2704891611 / 0.006352446 ]
P = $18500 / 42.58
P = $434.47
