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 correct is answer is a 9-sided polygon!
