A company determines that the profit, P(x), earned on the sale of x items is given
by the formula:
a) Determine the number of items sold if the company loses $2,400.

Thank you Answer by edjones(8007) (Show Source):
You can put this solution on YOUR website! P(x)= 20x - x^2
a)
20x-x^2=-2400
x^2-20x-2400=0
(x-60)(x+40)=0
x=60
.
b) As you can see by the graph below 10 items sold yield the maximum profit.
.
c) 20*10-10^2=$100
