Can you offer Econ help for this question????

A Bavarian crystal company designs and produces crystal wine decanters. The production manager estimates a total cost (TC) and marginal cost (MC) of production to be

TC=10,000 = 40 Q + 0.0025 Q2 and MC= 40 +0.005 Q

where Q is the number of wine decanters produced and revenues and costs are in dollars. Because the company is only one of many crystal producers in the market, it can sell as many many decanters it wants at the market price of $70. Because it is a price taker, its total revenue (TR) and marginal revenue (MR) are

TR= P x Q =70 Q and MR=70

a. Find the optimal level of production of wine decanter. Please show work

b. Calculate the total revenue (TR), total cost (TC), and net benefit (profit) from selling the optimal number of wine decanters
