Question

At a garage sale Petra priced her scooter for 15.50. She ended up selling it for 10.75. Find the percent of decrease in the price of the scooter. Round to the nearest tenth in necessary

Answer 1

In order to calculate the percent of decrease, you have to divide the difference between the two numbers by the original number and multiply the result for 100:

% decrease=((10.75-15.50)/15.50)*100

% decrease=-0.306*100

% decrease= -30.6%

According to this, the answer is that the percent of decrease in the price of the scooter is 30.6%.
