Subsistence Levels in Karim's Utility Function
Karim's utility function incorporates the concept of subsistence levels, which are minimum thresholds for free time and consumption. To derive any positive utility, his free time () must be greater than 6 hours and his consumption () must be greater than $45.

An individual's preferences for hours of daily free time (t) and units of consumption (c) are described by the utility function u(t,c) = (t-6)²(c-45). The individual is currently at a point where they have 16 hours of free time and 55 units of consumption. Which of the following alternative bundles would this individual prefer to their current situation?
Interpreting Utility Function Parameters
An individual's preferences for daily hours of free time (t) and units of consumption (c) are represented by the utility function u(t, c) = (t - 6)²(c - 45). What does this specific functional form imply about the individual's underlying preferences?
An individual's preferences for daily free time (t) and consumption (c) are represented by the utility function u(t, c) = (t - a)² * (c - b), where 'a' and 'b' are positive constants representing minimum required levels of free time and consumption, respectively. For any combination where t > a and c > b, what happens to this individual's willingness to give up consumption for an additional hour of free time as their amount of free time increases (while keeping their overall satisfaction level constant)?
An individual's preferences for daily hours of free time (t) and units of consumption (c) are represented by the utility function u(t, c) = (t - 6)²(c - 45). Consider the consumption bundle where t=20 and c=40. Which of the following statements most accurately describes the individual's assessment of this bundle based on the given utility function?
To algebraically verify that the indifference curves for the utility function u(t, c) = (t - 6)²(c - 45) are convex (i.e., they bow inwards toward the origin), a specific sequence of mathematical steps is required. Arrange the following key steps of this procedure into the correct logical order.

Calculating the Marginal Rate of Substitution
An individual's preferences for daily hours of free time (t) and units of consumption (c) are represented by the utility function u(t, c) = (t - 6)²(c - 45). At the point where the individual has 16 hours of free time and 55 units of consumption, what is the value of their Marginal Rate of Substitution (the rate at which they are willing to trade consumption for an additional hour of free time)?

An individual's satisfaction from their daily choices depends on two conditions being met simultaneously: they must have more than 6 hours of free time, and their consumption must exceed $45. If either of these minimum thresholds is not met, their satisfaction is zero or less. Which of the following daily outcomes would result in positive satisfaction for this individual?
Evaluating Job Offers with Minimum Thresholds
Comparing Outcomes with Minimum Satisfaction Thresholds
An individual's daily satisfaction is positive only if they have more than 6 hours of free time AND their consumption is greater than $45. Otherwise, their satisfaction is zero. Consider two possible daily outcomes:
- Outcome A: 15 hours of free time and $45 of consumption.
- Outcome B: 7 hours of free time and $46 of consumption.
How does the satisfaction derived from Outcome A compare to the satisfaction from Outcome B?
An individual's daily satisfaction is positive only if they have more than 6 hours of free time AND their consumption is greater than $45. Given this, a person with 10 hours of free time and exactly $45 of consumption will achieve a positive level of satisfaction.

Analyzing Policy Impact on Satisfaction with Subsistence Levels
An individual's daily satisfaction is positive only if they have more than 6 hours of free time AND their consumption is greater than $45. This individual has 24 hours available each day and earns a wage of $10 per hour. Which of the following work schedules would provide this individual with a positive level of satisfaction?
An individual's daily satisfaction is positive only if they have more than 6 hours of free time AND their consumption is greater than $45. For each scenario below, match it to the correct satisfaction outcome.
Job Offer Evaluation with Satisfaction Thresholds
An individual's daily satisfaction is positive only if they have more than 6 hours of free time AND their consumption is greater than $45. Otherwise, their satisfaction is zero. Consider two possible daily outcomes:
- Outcome A: 15 hours of free time and $45 of consumption.
- Outcome B: 7 hours of free time and $46 of consumption.
