Math Problem Statement
The total weekly revenue earned at Royal Ruby Retailers is given by R(p) = − 7 3 p2 + 154p where p is the price (in dollars) RRR charges per ruby. Use this function to determine the following. (a) Determine the weekly revenue, to the nearest dollar, when the price is set at $20/ruby. $ (b) Determine the weekly revenue, to the nearest dollar, when the price is set at $200/ruby. $ Interpret your result. The domain of the demand function includes p = $200. The range of the demand function includes p = $200. The range of the demand function cannot realistically include p = $200. The domain of the demand function cannot realistically include p = $200. (c) Determine the price RRR should charge in order to obtain a weekly revenue of $2,541.
