First, we have to find the payment due after the down payment:
2389.75 - 150 = 2239.75
Now, assuming that the amount of money paid never changes, we simply divide the total amount of money due by the total amount of months:
2239.75/24 = 93.32 (I rounded to the nearest hundredth)
It will be financed at about $93.32 a month.
