create a cost function in the form CA=mx+b where m is total cost per burger x is the number of burgers sold and b is fixed cost of per week

Question

m= 0.45

x= 450

b= 1077.5

how would this look as an equation which can be graphed because when I do it it looks like 0.45 x 450 + 1077.5

and when I try to put it on online graphing technologies it won't work, how should it look

Answer 1

The function is:

CA(x) = 0.45x + 1077.5

(or y = 0.45x + 1077.5)

This will graph into a line in a graphing tool like Desmos:

You'll notice that x = 450 is a point on the line where the cost = $1280
