To find the total amount of a 20% down payment on a $249,000 house, we must first convert this 20% to decimal form. We can do this by dividing by 100:

Now that we have the percentage in decimal form, we can multiply this amount by the total cost of the house - in this case, $249,000:

So now we know that
the total cost of the 20% down payment will equal $49,800.
