Question

Joseph withdrew a total of $700 from his bank account after seven transactions. What is the numeric equation using negatives to show the average change in his account during each transaction?

Answer 1

The average change in Joseph's account during each transaction is -$100.

Step-by-step explanation:

The numeric equation using negatives to show the average change in Joseph's account during each transaction can be calculated by dividing the total withdrawal of $700 by the number of transactions, which is 7. Since the withdrawals represent a decrease in Joseph's account balance, we use negative values. Therefore, the equation is:

-700 ÷ 7 = -100

This equation shows that Joseph's account balance decreased by an average of $100 during each transaction.
