I believe it is $0.50.
$2 divided by 4 equals $0.50.
The gievn equation is ,

where t is the time in seconds and h is the no.of hamburgers assembled.
put h = 2 in equation (1).

blank A assembles 2 hamburges in 22.6 seconds.
put h = 3 in equation (1)

blank B assembles 3 hamburgers in 33.9 seconds.
put h = 5 in equation (1)

blank C assembles 5 hamburgers in 56.5 seconds.
put h = 8 in equation (1)

blank D assembles 8 hamburgers in 90.4 seconds.
First, you know that the slope will be the same (3/2).
Plug in the points 0 for x and 7 for y in order to find b.
7=3/2*0+b
b=7
Then put the new slope and y-intercept into the equation:
y=3/2x+7
I will assume that the two equations are
1) y = -x^2 +2x + 4 and 2) x +y = 4
subtract 2 from 1 and you get
y -x - y = -x^2 + 2x + 4 - 4
-x = -x^2 +2x
x^2 -x -2x = 0
x^2 - 3x = 0
x(x-3)=0
x=0 and x - 3 =0
x=0 and x = 3
Then y = 4 - x
y = 4 - 0 and y = 4 -3
y = 4 and y =1
Solutions:
Points (0,4) and (3,1)
