1. The problem asks: Josie has 47 left in her checking account and writes a check for 55. What is her new balance? 2. Writing a check for 55 means subtracting 55 from her current balance of 47. 3. The expression is $47 - 55$. 4. Subtracting a larger number from a smaller number results in a negative number. 5. Calculate $47 - 55$: $$47 - 55 = 47 + (-55)$$ 6. To simplify, add the numbers considering the sign: $$47 + (-55) = -(55 - 47) = -8$$ 7. So, Josie's new balance is $-8$. This means Josie is overdrawn by 8.
