Please help on my elementary calculus hw :) - Stephany 2. A commodity has a demand function modeled by p = 1700 -0.016x, and a total cost function modeled by C = 715,000 + 240x. (a) Find the profit and marginal profit at 2 = 700 units. (b) What price yields the maximum profit. (c) Use differentials to approximate the change in profit as the number of units sold changes from 500 units to 525 units. 3. Use implicit differentiation...
