Final answer:
The 20% down payment is $49,000 and the mortgage loan amount is $196,000.
Step-by-step explanation:
To determine the 20% down payment and the amount of the mortgage loan, we can start by finding 20% of the purchase price.
20% of $245,000 = $49,000
So, the down payment would be $49,000.
To find the amount of the mortgage loan, we subtract the down payment from the purchase price.
$245,000 - $49,000 = $196,000
Therefore, the mortgage loan would be $196,000.
