Make a down payment of $1500 and finance the rest of $2 at 1.9% interest rate, making equal monthly payments for 5 years.

We know that we have to make a down payment of $1500 and finance the rest of $20000 at a 1.9% interest rate, making equal monthly payments for 5 years. Our first step to solve this problem would be to convert 5 years into months. 

1 year = 12 months 

12 * 5 = 60 months 

Therefore, in 5 years there are 60 months. 

Now lets solve this problem step by step. 

       Subtract the down payment from $20,000

$20000-$1500=$18500

       Multiply the remaining number by the interest rate. 

$18500 *1.9 = $35150 

       Divide 35150 by number of months in 5 years (60)

$35150 / 60 = $585 

       Therefore, you have to pay $585 per month.
