(Solved): help plz and thank you The total cost and the total revenue (in dollars) for the production and sale ...

The total cost and the total revenue (in dollars) for the production and sale of $$Q$$ ski jackets are given by $$C(Q)=24Q+20,115$$ and $$R(Q)=200Q?0.2Q^2$$ for $$0?Q?1000$$. Find the value of $$Q$$ Where the greph of $$R(Q)$$ has a horizontal tangent line. Hint: The graph of R(Q) has a horizontal tangent line when the firet derivative of $$R(Q)$$ equals 0 . R(Q) has a horizontal tangent line at $$\mathbf{Q}=$$ (Enter your response as a whole number) Find the profit function $$P(Q)$$. Hint: The formula for the profit function is $$P(Q)=P(Q)=C(Q)$$ The profit function $$P(Q)$$ = (Enter a simplifed expression using $$Q$$ as the verlable and use minus signs if necessary). Find the value of $$Q$$ where the graph of $$P(Q)$$ has a horizontal fangent line. Hint The graph of $$P(Q)$$ has a horizontal tangent line when the first defivative of $$P(Q)$$ equals $$O$$. $$P(O)$$ has a horizontal tangent fine at $$Q=$$ (Enter your nesponse as a whole number.)
