The price of a plane ticket has increased from $150 to $200. By what percent has the price increased?
To calculate the percent increase, we can use the formula:
Percent Increase = ((New Price - Old Price) / Old Price) x 100%
Plugging in the values:
Percent Increase = (($200 - $150) / $150) x 100%
Percent Increase = ($50 / $150) x 100%
Percent Increase = 0.3333 x 100%
Percent Increase = 33.33%
Therefore, the price of the plane ticket has increased by 33.33%.
