Answer 1

The expression to show how Karen's bank account changed is 3000 - 3×800.

Step-by-step explanation:

The expression to show how Karen's bank account changed is 3000 - 3×800.

Let's break down the expression. Karen started with $3000 in her bank account and wrote rent checks for June, July, and August. The monthly rent is $800, so Karen wrote a total of 3 rent checks. Since she wrote the checks, we subtract this amount from her starting balance.

Therefore, the expression that represents how Karen's bank account changed is 3000 - 3×800.
