Question 990519: Determine the profit function for the given revenue function and cost function.
R(x) = 128x; C(x) = 76.5x + 8755
p(x)= x ????
how do i determine the break even point for
x=

You can put this solution on YOUR website!
P%28x%29=R%28x%29-C%28x%29
P%28x%29=128x-%2876.5x%2B8755%29
P%28x%29=128x-76.5x%2B8755
P%28x%29=51.5x%2B8755

.
The breakeven point occurs when P%28x%29=0
+51.5x%2B8755=0
51.5x=-8755
x=-8755%2F51.5
x=-170
That number doesn't make sense.
Issue here is that even when you make 1 widget, you're already making profit since the revenue function is greater than cost function for all x%3E0.
