Suppose that we're making and selling some widget and the profit (in dollars) when making *z* widgets is P(*z*) = 50*z* - 0.06*z*^2* - 650. Find the marginal profit formula and the marginal average profit formula. Then determine the marginal profit and the marginal average profit when 45 widgets are made. The marginal profit function is P'(*x*) = If we're already making 45 widgets and if we increase production by one widget our profit will change by $☐. The marginal average profit function is P'(*x*)= If we're already making 45 widgets and if we increase production by one widget our average profit per widget will change by $☐. Note: You can earn partial credit on this problem.

Problem 3 (Chain Rule and Implicit Differentiation): Consider a surface given by the equation below: ylnz + ze^(x) + tan(y) = e. Note that you cannot easily write z as a function of x and y. (1) Use implicit differentiation to find (∂z)/(∂x) at the point (1,0,1). (2) Use implicit differentiation to find (∂z)/(∂y) at the point (1,0,1).
