The Ali Baba Co. is the only supplier of a particular type of Oriental carpet. The estimated demand for its carpets is

Q = 112,000 − 500P + 5M

where Q = number of carpets, P = price of carpets (dollars per unit), and M = consumers’ income per capita. The estimated average variable cost function for Ali Baba’s carpets is

AVC = 200 − 0.012Q + 0.000002Q2
