Step-by-step explanation:

Because the school cafeteria can hold at most 150 people, the equation would be this: (p = people)

p ≤ 150

The number line would have a closed dot at 0, a closed dot at 150, and a line connecting the two.

I hope this helps :)

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

huh? im pretty sure it is in 199
