Answer:
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%
