Airfare cost \( \$ 200 \) in 2020. In 2022, it cost \( \$ 259.68 \)

To find the percentage increase in airfare cost from 2020 to 2022, we can use the formula: \[ \text{Percentage Increase} = \left( \frac{\text{New Value} - \text{Old Value}}{\text{Old Value}} \right) \times 100\% \] Given: - Old Value (2020) = $200 - New Value (2022) = $259.68 Substitute the values into the formula to find the percentage increase in airfare cost. Calculate the value by following steps: - step0: Calculate: \(\frac{\left(259.68-200\right)}{200}\times 100\) - step1: Remove the parentheses: \(\frac{259.68-200}{200}\times 100\) - step2: Subtract the numbers: \(\frac{59.68}{200}\times 100\) - step3: Divide the terms: \(\frac{373}{1250}\times 100\) - step4: Reduce the numbers: \(\frac{373}{25}\times 2\) - step5: Multiply: \(\frac{373\times 2}{25}\) - step6: Multiply: \(\frac{746}{25}\) The percentage increase in airfare cost from 2020 to 2022 is 29.84%.
