If R(x)=6x and C(x)=.005x^2+2.9x+40.
a.) P(x)
b.) R(150), C(150), and P(150)
c.) R (x), C (x), and P (x)
d.) R (150), C (150), and P (150)?

Question

paramvenu · Accepted Answer

a)R(x) = 6x
C(x) = 0.005x^2 + 2.9x + 40
P(x) = R(x) - C(x)
= [6x] - [0.005x^2 + 2.9x + 40]
= 6x - 0.005x^2 - 2.9x - 40
= - 0.005x^2 + 3.1x - 40

b) Just substitute x = 150 in the relevant functions

c) Same as (a)

d) Same as (b)
