The cost of producing a number of items x is given by: C = mx + b

In which b is the fixed cost and m is the variable cost (the cost of producing one more item).
(a) If the fixed cost is $40 and the variable cost is $10, write the cost equation.and then graph

A) C=10x+40
C=10*0+40
C=40
to graph this it would be (0,40)
C=10*1+40
C=10+40
C=50
to graph it would be (0,50)

the next part
The revenue generated from the sale of x items is given by R = 50x. Graph the
revenue equation on the same set of axes as the cost equation.
MY A) R=C
50x=10x+40
50*0=10*0+40
0=40

50*1=10*1+40
50=50

I am not sure if i did this part right
I do not know what to graph any help would be appreciated



How many items must be produced for the revenue to equal the cost (the
break-even point)? I can not get to solve this part yet until i figure the other out








On the revenue function, graph y= 50 x
that is the equation.

for breakeven, do what you did in the revenue section. Set R= C and solve for x.
