What is 15% of 200?

1. 20

2. 25

3. 30

4. 35

The correct answer is: 30

To find 15% of 200, you can use the formula for percentage calculation, which is: \[\text{Percentage} = \left(\frac{\text{Percentage Rate}}{100}\right) \times \text{Total}\] In this case, the percentage rate is 15 and the total is 200. Plugging these values into the formula gives: \[ 15\% \text{ of } 200 = \left(\frac{15}{100}\right) \times 200 \] Calculating this step-by-step: 1. Convert the percentage to a decimal: \( \frac{15}{100} = 0.15 \). 2. Multiply this decimal by 200: \( 0.15 \times 200 = 30 \). So, 15% of 200 equals 30. This confirms that the calculation is accurate. The other choices do not result from correctly applying the percentage calculation. For example, 20 (which is 10% of 200) and 25 (which is 12.5% of 200) do not represent 15%. Likewise, 35 is also not a correct calculation for 15% of 200. The
