Question 1187308: Find the maximum profit and the number of units that must be produced and sold in order to yield the maximum profit. Assume that revenue,R(x), and cost,C(x), are in thousands of dollars, and x is in thousands of units.
R(x)=7x-2x^2, C(x)=x^3-3x^2+2x+1

R-C=Profit=-x^3+x^2+5x-1
Take the derivative and set it equal to 0.
-3x^2+2x+5=0=3x^2-2x-5=(3x-5)(x+1)=0
x= 5/3 as only positive root.
f(5/3)=(-125/27)+25/9+25/3-1=(1/27)(-125+75+225-27)=(148/27)=$5.48 thousands
