To determine how much Margo saves each month, we can calculate 22% of her $2500 paycheck.
Step 1: Calculate 22% of $2500.
To find 22%, we convert the percentage to a decimal: \[ 22% = \frac{22}{100} = 0.22 \]
Now, multiply this by her monthly paycheck: \[ \text{Savings per month} = 0.22 \times 2500 \]
Calculating that: \[ \text{Savings per month} = 0.22 \times 2500 = 550 \]
Step 2: Calculate annual savings.
If Margo saves $550 each month, then to find her savings for a year, multiply her monthly savings by 12: \[ \text{Annual Savings} = 550 \times 12 = 6600 \]
So, after a year of saving, Margo will have saved $6,600.
The correct answer is \( \text{$6,600} \).
