Carlos is a hard-working college senior. One Thursday, he decides to work nonstop until he has answered 250 practice problems for his math course. 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 AM. 0 9 100 10 175 11. 225 12. 250 The marginal, or additional, gain from Carlos's second hour of work, from 9:00 AM to 10:00 AM, is ___ problems. he marginal gain from Carlos's fourth hour of work, from 11:00 AM to noon, is ___ problems. 2. Later, the teaching assistant in Carlos's math course gives him some advice. "Based on past experience," the teaching assistant says, "working on 37.5 problems raises a student's exam score by about the same amount as reading the textbook for 1 hour."

Because of the violent nature of the sport, professional American football players are at risk of suffering concussions (or brain injuries) during the violent collisions that occur between players during the game. Violent collisions involving hits to the head are particularly risky. Suppose the commissioner of the National Football League (NFL) institutes a rule requiring players to wear a new, lighter helmet that is designed to reduce head trauma during collisions between players on the field. While the new helmets _____ the probability of a concussion resulting from each individual collision, at the same time the new helmets could also give football players an incentive to play more ____ , which could potentially ______ the amount of violent collisions and thus the number of concussions suffered by NFL players, all else equal.

Juanita is deciding whether to buy a suit that she wants, as well as where to buy it. Three stores carry the same suit, but it is more convenient for Juanita to get to some stores than others. Juanita makes $16 an hour at work. She has to take time off work to purchase her suit, so each hour away from work costs her $16 in lost income.
