Questions: 3. Scenario: Opportunity cost and marginal analysis Jake has training for basketball Jake has only 15 hours available to devote to his training this week. Each hour he spends doing cardio burns 500 calories and each hour he spends lifting weights burns 300 calories. His coach has told him he needs to burn at least 6000 calories during his training this week. Which best principle or individual choice do these statements best illustrate? O Jake can use time more efficiently by spending the entire amounts of time doing cardio. O People face trade-offs. O Jake has an incentive to spend more time on shooting and dribbling. O Jake can use time more efficiently by spending the entire amounts of time lifting weights.

The answer is "People face trade-offs."

While spending all his time on cardio would maximize calorie burn, it may not be the most efficient use of his time if he needs to balance other aspects of his training, such as strength building through weight lifting.

This option best illustrates the principle at play. Jake has a limited amount of time (15 hours) and must decide how to allocate it between cardio and weight lifting to meet his calorie-burning goal. This decision involves trade-offs, as spending more time on one activity means less time for the other.

The scenario does not mention shooting and dribbling as part of Jake's training requirements or goals, so this option is not relevant to the given situation.

Similar to Option 1, focusing solely on weight lifting may not be the most efficient use of Jake's time if his goal is to burn a specific number of calories, as cardio burns more calories per hour.
