Evaluating an Economic Model
A student is modeling their weekly trade-off between working at a part-time job and enjoying leisure time. They have 40 hours available each week for these two activities and earn a constant wage of $15 per hour.
They create a graph where the vertical axis represents 'Total Weekly Income' and the horizontal axis represents 'Hours of Leisure Time'. The resulting graph is a single, straight, downward-sloping line.
A classmate claims the model is flawed, arguing that a graph showing income should always have an upward slope because working more hours leads to more income.
Evaluate the student's original graph. Is it a valid way to represent the trade-off described? Justify your conclusion by explaining what the slope of the line represents in this specific context.

An individual earns a constant wage for each hour they work. Consider two different graphs representing this situation:
- Graph A: Plots total income on the vertical axis against hours worked on the horizontal axis.
- Graph B: Plots maximum possible consumption (which is equal to income) on the vertical axis against hours of free time on the horizontal axis, out of a total of 24 available hours per day.
How do the slopes of the lines on these two graphs relate to the hourly wage?
Evaluating Work-Leisure Graphs
An individual's financial situation is represented by two graphs: one plotting total income against hours worked, and another plotting maximum consumption against hours of free time. If this individual's hourly wage increases, the slope of the income graph becomes steeper, while the slope of the consumption graph becomes flatter.
Interpreting Economic Trade-off Graphs
An individual's choice between work and leisure can be represented graphically in two ways. Match each characteristic below to the correct type of graph: the 'Income Function' (which plots income against hours worked) or the 'Budget Constraint' (which plots consumption against hours of free time).
Evaluating an Economic Model
An individual's daily income (I) is determined by the number of hours they work (L) at a constant hourly wage. This relationship is represented by the equation: I = 15L.
This same individual's daily consumption possibilities (c) can be represented as a function of their hours of free time (t), assuming they spend all their income on consumption and have 24 hours available each day.
Which of the following equations correctly represents the relationship between their maximum possible consumption and their free time?
Explaining Mirrored Economic Graphs
An economist creates two graphs to represent an individual's daily earning and spending possibilities, based on a constant hourly wage. Graph A plots 'Daily Income' against 'Hours of Work'. Graph B plots 'Maximum Daily Consumption' against 'Hours of Free Time' (out of 24 total hours). Both graphs depict a straight line. Which statement best describes the relationship between the lines on Graph A and Graph B?
