We know that
• Jen had $567.12 (initial balance).
,
• She deposited $80.
,
• She deposited again $240.63.
,
• She wrote a check for $79.50.
Each deposit represents a positive number, and the check represents a negative number because it's money spent. So, let's represent the situation as an algebraic sum

First, we add the positive numbers

Then, we subtract the numbers

Therefore, Jen's balance now is $808.25.
