Question

Graph the cost and revenue functions
C = 0.07x + 32000
R = 0.28x
in the same viewing rectangle.
a) Find the sales x necessary to break even
(R = C).
Answer in units of units

Answer 1

simply graph y = 0.07x + 32000 and y = 0.28x and see the x-value where the two lines intersect. As for units, you may need to refer to earlier parts of the exercise to figure out exactly what the units are (probably thousands or tens of thousands perhaps)
