Later, the teaching assistant in Beth's math course gives her some advice.

For simplicity, assume students always cover the same number of pages during each hour they spend reading.arrow_forwardBobby has been recently hired to work on a highway construction crew for the summer. The work is hard, but the pay is great at a time when jobs are hard to come by. One day, the foreman told Bobby to slow down. "You're working too hard." This crew is used to taking it easy. "At this rate, you'll be out of a job because once we're done with this project, you're finished! Work slower - you'll last a lot longer." Bobby is convinced that this practice is dishonest to the company and to the taxpayers who are paying for the highway work. But he needs the job to meet his school expenses.

Similar buildings in the neighborhood rent for $4000 per month. Jill is considering selling her building and renting space in the suburbs for $3000 per month. Jill decides not to make the move. She reasons, "I would like to have a restaurant in the suburbs, but I pay no rent for my restaurant now, and I don't want to see my costs rise by $3000 per month." What do you think of Jill's reasoning? Chose the best answer: A) Jill's reasoning is correct. Why move and have to start writing a check for $3000 rent when she doesn't pay rent right now on the building she owns in the city? B) Jill's reasoning is faulty. There is an opportunity cost associated with building she owns. It is mentioned she could likely rent out her building in the city for $4000, which would more than cover her $3000 rent in the suburbs. Opportunity costs of "self-employed" resources, whether Jill's labor…arrow_forward

If I produce 10,001 pizzas, my total cost will rise to $50,011. Therefore, my marginal cost of producing pizzas must be increasing." ( 1.) Using the point drawing tool, indicate the point of marginal cost. Label this point "Marginal cost." 2.) Using the point drawing tool, indicate the point of average total cost.
