explain

To calculate the percent increase, you use the formula:

((new value - old value) / old value) x 100

In this case, the old value was $150 and the new value is $200:

((200 - 150) / 150) x 100 = (50 / 150) x 100 = 0.33 x 100 = 33%

Therefore, the price of the plane ticket has increased by 33%.
