Section 1: Getting Started 21
Example: Suppose you’ve written three checks without updating your
checkbook, and you’ve just deposited your paycheck for $1,053.00 into your
checking account. If your latest balance was $58.33 and the checks were written
for $22.95, $13.70, and $10.14, what is the new balance?
Solution: When written down on paper, this problem would read
58.33 – 22.95 – 13.70 – 10.14 + 1053
