Equation of Karim's Indifference Curve
The equation for any of Karim's indifference curves is established by setting his specific utility function equal to a constant utility level, . This yields the formula . This equation, which defines a specific curve for each value of , can be algebraically rearranged to express one variable in terms of the other, for instance, to isolate consumption () and see how it depends on free time () along that curve.

An individual's preferences for hours of free time per day (
t) and units of consumption (c) are represented by the utility functionu(t, c) = t * c. If this individual currently has 20 hours of free time and 80 units of consumption, which equation represents the indifference curve passing through this specific combination of goods?Deriving and Interpreting an Indifference Curve Equation

Comparing Bundles on an Indifference Curve
An individual's preferences for two goods, Good X and Good Y, are described by the utility function u(X, Y) = X²Y. If the individual is currently consuming a bundle of 4 units of Good X and 10 units of Good Y, which of the following bundles would provide the exact same level of satisfaction?
Consider an individual whose preferences for daily hours of free time (
t) and units of consumption (c) are represented by the utility functionu(t, c) = t + 2c. This individual would strictly prefer the combination of 10 hours of free time and 5 units of consumption over the combination of 6 hours of free time and 7 units of consumption.An individual's preferences for two goods, apples (A) and bananas (B), are such that they are always willing to trade one apple for exactly two bananas to maintain the same level of satisfaction, regardless of how many of each they currently have. Which equation best represents an indifference curve for this individual, where
ūis a constant level of utility?Match each utility function, which describes an individual's preferences over two goods (x and y), with the corresponding description of the preferences it represents. An indifference curve is formed by setting each function equal to a constant.
An individual's preferences for two goods, x and y, are represented by the utility function
u(x, y) = x * y. If this individual is consuming a bundle of 10 units of good x and 5 units of good y, the equation for the indifference curve passing through this point isx * y = ____.An economist has a utility function representing a consumer's preferences for two goods, X and Y. The economist wants to find the equation for the specific indifference curve that passes through the consumer's current consumption bundle. Arrange the following steps in the correct logical order to accomplish this.

Karim's Indifference Map
An individual's preferences for daily free time (t, in hours) and consumption (c, in dollars) can be represented by a set of curves defined by the equation (t - 6)(c - 45) = k, where k is a constant representing a specific level of satisfaction. If this person is currently satisfied with 16 hours of free time and a consumption of $55, what level of consumption would be required to maintain the exact same level of satisfaction if their free time were to decrease to 11 hours?

Comparing Consumption Bundles
A person's preferences for daily free time (t, in hours) and consumption (c, in dollars) are modeled by a family of curves where
(t - 6)(c - 45) = k, andkis a positive constant representing a specific level of satisfaction. Based on this model, a combination of 5 hours of free time and $100 of consumption would yield a positive level of satisfaction.Interpreting Utility Function Parameters
An individual's preferences for daily free time (t, in hours) and consumption (c, in dollars) are modeled by a set of indifference curves where
(t - 6)(c - 45) = k, withkrepresenting the level of satisfaction. Match each consumption bundle in the left column with a bundle from the right column that provides the exact same level of satisfaction.Evaluating Trade-offs Along a Satisfaction Curve
An individual's satisfaction from daily free time (t, in hours) and consumption (c, in dollars) is described by an equation where
(t - 6)(c - 45) = u, anduis a constant value representing the level of satisfaction for a specific preference curve. For this individual, the combination of 10 hours of free time and $95 of consumption provides the exact same level of satisfaction as 26 hours of free time and $55 of consumption. The constant level of satisfaction,u, for this specific preference curve is ____.Consider an individual whose preferences for daily free time (t, in hours) and consumption (c, in dollars) are represented by the family of curves where
(t - 6)(c - 45) = k, withkbeing a positive constant for any given curve. This equation implies that to maintain the same level of satisfaction, the amount of consumption the individual is willing to give up for one additional hour of free time is constant, regardless of how much free time they currently have.
