1. If the monthly demand function is p = 7230 - 5q2 and the supply function before taxation is p = 30 + 30q2, what tax per item will maximize the total tax revenue? 2. For the following demand equation, p(q) = 20 - 0.1581 q find the revenue equation, sketch the graph of the revenue equation, label where the revenue graph is increasing and where it is decreasing, 3. For the following function, q = 40(20 - p)2,0
