Question 1164161: Total profit is defined as total revenue, R(x), minus total cost, C(x), and is given by the function P(x)=R(x)-C(x). Given R(x)=60-0.4x^2 and C(x)=5x+15 , find each of the following.
a) P(x)
b) R(70), C(70), and P(70) Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! P(x)=difference in the binomials
-0.4x^2+60
-{5x+15)
This is -0.4x^2-5x+45
R(70)=60-0.4*4900=-1900
C(70)=365
P(70)=-$2265 from above
or -0.4(4900)-5(70)+45
=-$2265
