Expert Solution
Step 1

(a)

The revenue function is product of quantity demanded times the demand function.

So, R(x)=x·p=x(700-0.06x)=700x-0.06x2.

The profit function is just the difference of revenue function and cost function.

So, P(x)=R(x)-C(x)=700x-0.06x2-(0.000005x3-0.03x2+530x+75000)                         =-0.000005x3-0.09x2+170x-75000

(b)

Marginal cost is the first derivative of cost function.

So, C'(x)=0.000015x2-0.06x+530.

The marginal revenue is the first derivative of the revenue function.

So, R'(x)=700-0.12x.

The marginal profit is the first derivative of profit function.

So, we get P'(x)=-0.000015x2-0.18x+170.
