The manager of a restaurant found that the cost to produce 200 cups of coffee is $20.15, while the cost to produce 500 cups is $548.35. assume the cost c(x) is a linear function of x, the number of cups produced. answer parts a through f.
a. find a formula for c(x).

C(x)=1.76067x - 331.98

Step-by-step explanation:

We are given two points (x,y) of the linear function C(x):

P1 = (200; 20.15) and P2 = (500; 548.35)

The slope of the function, 'm', can be found by:

Applying point P1 to the general linear equation gives us C(x):

the answer is c.

step-by-step explanation:

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
