Tricia has lost money on a particular stock for the past three years. Thus, she believes the stock will have a high positive rate of return this year because earning a good return is long overdue. This assumption is best described as the: law of small numbers. house money effect. gambler's fallacy. false consensus. recency bias.

Until recently, hamburgers at the city sports arena cost $4.70 each. the food concessionaire sold an average of 13 comma 000 hamburgers on game night. when the price was raised to $5.40, hamburger sales dropped off to an average of 6 comma 000 per night. (a) assuming a linear demand curve, find the price of a hamburger that will maximize the nightly hamburger revenue. (b) if the concessionaire had fixed costs of $1 comma 500 per night and the variable cost is $0.60 per hamburger, find the price of a hamburger that will maximize the nightly hamburger profit.
