The price of a plane ticket has increased from $150 to $200 by what percent has the price increased

To calculate the percentage increase, we use the formula:

Percentage increase = ((New Price - Original Price) / Original Price) * 100

In this case, the original price is $150 and the new price is $200:

Percentage increase = (($200 - $150) / $150) * 100
Percentage increase = ($50 / $150) * 100
Percentage increase = 0.3333 * 100
Percentage increase = 33.33%

Therefore, the price of the plane ticket has increased by 33.33%.
