b) Determine the sale price where the elasticity is unit

c) Show whether the quantity where costs are minimized is maximized utility.

d) With the given approach. Design (write) a question related to differential calculus and solve it.

U(9)=-1.05q + 25069 - 70000 3 C(q) = q* -69 + 70000 U(9)=-1.05q + 25069 - 70000 3 C(q) = q* -69 + 70000
