Change in price = (new) - (old) = 19 - 25 = -6

Divide the change in price over the original price: -6/19 = -0.315789 (result is approximate)

Now multiply by 100 to convert to a percentage: 100*(-0.315789) = -31.5789%

Percent Change = -31.5789% which is another way to say "a decrease of 31.5789%"

Question: What is the percent decrease?
Answer: 31.5789%

Note: The answer above is approximate. Round that however you need to or however the instructions state.
