Final answer:
To calculate the percentage increase from 2000 to 2400, you subtract the original value from the new value, divide by the original value, and multiply by 100. This results in a percentage increase of 20%.
Step-by-step explanation:
The percentage increase from 2000 to 2400 can be calculated using the formula for percentage change, which is ((new value - original value) / original value) × 100%. To apply this to the given values:
- Subtract the original value (2000) from the new value (2400) to find the increase in value, which is 2400 - 2000 = 400.
- Divide this increase (400) by the original value (2000), so 400 / 2000 = 0.20.
- Multiply the result by 100 to find the percentage increase, so 0.20 × 100% = 20%.
Therefore, the percentage increase from 2000 to 2400 is 20%, which corresponds to option C.
