Answer:
$2592
Explanation:
Let the amount of loan applied for by both person be $x and $y respectively. If their loan differs by $72 each month, the second person would have applied for $(x+72) each month.
Amount applied by first person will be $x at the end of first month
Amount applied by second person will be $(x+72) at the end of first month
At the end of 36 months, the amount applied for by the first man will be $36x
At the end of 36 months, the amount applied for by the second man will be $36(x+72)
First person 'x' =$36x
Second person 'y' = $36(x+72)
If x pays $36x
y will pay $(36x+2592)
Their difference will become
$36x+$2592-$36x
= $2592
The person with the lower credit score will pay $2592 at the end of the 36-month loan
