Barbara owns the sole hairdressing salon in a small country town. She has estimated the demand and marginal revenue for her product.
They are P = 84 - 2Q (quantity) and MR = 84 - 4Q, respectively. She also experiences a constant marginal cost of $16.
A) What is Barbara’s profit-maximising quantity?
B) What price should Barbara charge at that profit-maximising quantity?
C) Assume the average total cost (ATC) at the profit maximising output is $20. Calculate the profit or loss Barbara makes.
D) Barbara is considering expanding the size of her salon and increasing daily output to Q = 25. Is this a good/bad idea? Why/why not?
Thank you!
