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 the percent to the nearest tenth if necessary.

percent decrease is 30%

Step-by-step explanation:

Step one:

given data

Cost of scooter= $15.50

selling price= $10.75

Step two:

%decrease = Cost price-selling price/cost price

%decrease = (15.5-10.75/15.5)*100

%decrease =( 4.75/15.75)*100

%decrease = 0.30*100

%decrease =30%

therefore the percent decrease is 30%
