Dealership 4: he would pay $40.33

Step-by-step explanation: I used a calculator, so if you have 1/3 you put 1 divided by 3 in your calculator and right that down somewhere completely

Then, you divide $121 dollars by the number you got for 1 divided by 3 and then multiply it by 121 and should get 40.3333333333 but you round to the nearest tenth so it would by 40.33

1÷3= 0.33333333333

121×0.33333333333= 40.3333333333

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
