Final answer:
After subtracting the check amount from Mr. Sanchez's original bank balance, his new balance is -$6.26, meaning his account is overdrawn.
Step-by-step explanation:
The student is dealing with a straightforward subtraction problem in mathematics, where they need to calculate the new balance in Mr. Sanchez's bank account after writing a check that exceeds the current balance. Initially, Mr. Sanchez has $293.74 in his account. After he writes a check for $300, we subtract the amount of the check from the starting balance to find the new balance. The calculation follows:
$293.74 - $300.00 = -$6.26
Therefore, Mr. Sanchez's new balance is -$6.26, which indicates that his account is now overdrawn by this amount.
