Question

Given cost and revenue functions, find the profit function.
P(x) = R(x)-C(x)

Answer 1

\[\huge R(x)= \frac{ 575 }{ 2\sqrt{x}}-3 \]

Answer 2

\[\huge C(x)= 2000+150x-0.002x^2\]

Answer 3

What seems to be the problem?

Answer 4

@Mertsj i cant seem to subtract them

Answer 5

That's because there are no like terms so why don't we just write:
\[P(x)=\frac{575\sqrt{x}}{2x}+0.002x^2-150x-2003\]
