Differentiating the Feasible Frontier Using the Chain Rule
Calculating and Interpreting the Rate of Transformation
A self-employed artisan's daily production of widgets (W) is a function of the hours they work (h), given by the function W = 20√h. Working hours are determined by the hours of free time (t) in a 24-hour day, such that h = 24 - t. Calculate the rate at which widget production changes with respect to free time (dW/dt) at the point where the artisan is taking 15 hours of free time. Briefly explain the practical meaning of your calculated value.

MRT as the Marginal Product of Labor
A student's final grade (G) is a function of the hours they study (h), represented by the equation G = 10√h. The hours of study are determined by the hours of free time (t) in a 24-hour day, where h = 24 - t. What is the derivative of the grade with respect to free time (dG/dt)?
Calculating and Interpreting the Rate of Transformation
A student's final grade (G) in a course is a function of the hours they study (h), represented by the equation G = 10√h. The hours of study are determined by the hours of free time (t) in a 24-hour day, where h = 24 - t. To find the rate at which the grade changes with respect to free time (dG/dt), one must break the problem into parts. Match each component of this calculation with its correct mathematical expression.
A student's grade (G) in a course is determined by their hours of study (h), according to the function G = 8√h. The hours they can study are constrained by the 24 hours in a day, such that h = 24 - t, where 't' is hours of free time. To find the rate at which the grade changes for each additional hour of free time (dG/dt), you must use the rule for differentiating a composite function. Arrange the following steps into the correct logical sequence for finding this rate.
Farmer's Production and Leisure Trade-off
A student's potential exam score (y) is a function of the hours they study (h), given by the equation y = 5h². The hours they study are constrained by the 24 hours in a day, such that h = 24 - t, where t represents hours of free time. A student incorrectly claims that the rate of change of the score with respect to free time (dy/dt) is 10h.
Rationale for a Differentiation Method in an Economic Model
A student's potential exam score (S) is a function of the hours they study (h), represented by the equation S = f(h). The hours they study are constrained by the 24 hours in a day, such that h = 24 - t, where t represents hours of free time. The rate at which the score changes with respect to free time (dS/dt) can be found by multiplying the rate of change of the score with respect to study hours (dS/dh) by the rate of change of study hours with respect to free time (dh/dt). Given this information, the numerical value for dh/dt is ____.
Analyzing a Manager's Profit Calculation
A firm's daily revenue (R) is a function of the number of widgets (q) it sells, described by the function R = f(q). The number of widgets sold is, in turn, a function of the daily advertising budget (a), described by q = g(a). To understand the impact of advertising on revenue, the firm needs to find the rate of change of revenue with respect to the advertising budget (dR/da). Which of the following statements correctly describes how to calculate this rate of change by breaking it down into its intermediate components?
