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%
The graph means that 2 x and 9.4 make up 20 in total, so set up the equation 2x + 9.4 = 20.
Subtract 9.4 from both sides.
2x = 10.6
Divide by 2.
x = 5.3
The answer is the value of x that makes this equation true is 5.3
