Answer:
The student had $50 in his account before writing the $500 check.
Explanation:
To find the answer, we can deduct the amount of the check from the current balance.
The current balance in the student's account is $550.
By subtracting the amount of the check ($500) from the current balance ($550) we get the amount in the student's account before the check was written.
$550 - $500 = $50
