He starts work at 8:00 AM and uses a table to keep track of his progress throughout the day. He notices that as he gets tired, it takes him longer to solve each problem. Time Total Problems Answered 8:00 AM 0 9:00 AM 50 10:00 AM 80 11:00 AM 100 Noon 110 Use the table to answer the following questions. The marginal, or additional, gain from Jake’s first hour of work, from 8:00 AM to 9:00 AM, is problems. The marginal gain from Jake’s third hour of work, from 10:00 AM to 11:00 AM, is problems. Later, the teaching assistant for Jake’s economics course gives him some advice. “Based on past experience,” the teaching assistant says, “working on 25 problems raises a student’s exam score by about the same amount as reading the textbook for 1 hour.” For…

Give typing answer with explanation and conclusion Consider a good or service where consumers pay more than its actual valuation (for eg, products with markup prices at retail significantly higher than their cost: greetings cards, bottled water, stock price, movie theatre popcorn/candy). Based on the irrational decision-making and marginal analysis, explain why such irrational decision-making could take place in this situation.
1. The rules regarding economic decision maker behavior are: Group of answer choices A: Consumers behave rationally and maximize utility, but producers do not behave rationally B: Producers behave rationally and maximize profits, but consumers do not behave rationally C: consumers are ratiional and maximize utility, and producers are rational and maximize profits D: Consumers maximize total consumption, and producers maximize production
Oscar purchased a $30 steak for dinner, but burned it bad on the grill. Since he paid top dollar for the steak he figures he should eat it anyways. Is Oscar properly using economic reasoning? Yes, the marginal cost of not eating the steak would be $30. No, the $30 spent on the steak is a sunk cost and should not be included in his decision whether to eat the steak or not.. Yes, if he doesn't eat the steak he will have wasted economic resources. No, the opportunity of eating the steak is whatever else he could have purchased for the $30.
