Teresa is buying a car for $23,550. she will finance $19,600 of it with a 2-year loan at 2.7% apr. what will her monthly auto payment be?

Present value of annuity = 12P(1 - (1 + r/12)^-12n) / r
19,600 = 12P(1 - (1 + 0.027/12)^-(2 x 12)) / 0.027
0.027 x 19600 = 12P(1 - (1 + 0.00225)^-24)
529.2 = 12P(1 - (1.00225)^-24)
12P = 529.2 / (1 - 0.9475) = 529.2 / 0.0525
P = 10,077.9995 / 12 = $839.83

Therefore, her monthly payment = $839.83

It is a percent with money involved too divide and you should have your answer
