To find out how much Annie will be depositing into her savings account, we need to first calculate the total amount of the checks she is depositing and then subtract the cash she wants to receive.
Here are the amounts of the three checks:
- Check 1: $50.32
- Check 2: $324.89
- Check 3: $753.15
First, we'll sum the amounts of the checks:
\[ 50.32 + 324.89 + 753.15 = 1,128.36 \]
Next, we need to subtract the cash amount that Annie wants to receive:
\[ 1,128.36 - 137.82 = 990.54 \]
Therefore, the amount that she will be depositing into her savings account is $990.54.
The answer is a. $990.54.
