A. 37
B. 27
C. 32
D. 48

Answer 1

If they work continuously for 8 hours they can bake 32 cookies but that's a really long time to bake lol

Explanation:

Answer 2

C. 32

Explanation:

First we can find the equation of the graph using the points (5,20) and(0,0).

Let x represent hours and y represent batches of cookies

slope = (20 - 0)/(5 - 0)

= 20/5

= 4

Now use a general point (x,y) and (5,20) to find the equation.

4 = (y - 20)/(x - 5)

4(x-5) = y-20

4x - 20 = y - 20

y = 4x

when x = 8,

y = 4×8

= 32.
