Find the PERCENT of Change.
The original cost was $50 and the new cost is $200.

300%

Step-by-step explanation:

To find percent change we need to use this formula:

To find the amount of change we need to minus 50 from 200:

200 - 50 = 150

Now that we have the amount of change we can plug it in to the equation with the original amount (50):

Therefore, the percent of change is 300%.
