Find the number that goes in the missing box

28

Step-by-step explanation:

The y, Cost, seems to increase by 6 every ride. Using this idea adding 6 to 22 gives 28.

28

Step-by-step explanation:

1 -> 16 = 15 + 1

2 -> 22 = 20 + 2

3 -> 28 = 25 + 3

4 -> 34 = 30 + 4

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

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
