After the booster club sold 40 hotdogs at a football game, it had $90 in profit. After the next game, it had sold a total of 80 hotdogs and had a total of $210 in profit. Which equation models the total profit, y, based on the number of hotdogs sold, x?

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

(-1,-0.5)

step-by-step explanation:

a)(x-2)^2+(y-1)^2=9
