To plot the demand schedules for Alex, Becky, and the total market, follow these steps:

Step 1: Create the Axes

• X-axis (Horizontal): Represents the price per pair of jeans (in dollars).
• Y-axis (Vertical): Represents the quantity of jeans demanded (in pairs).

Step 2: Plot Alex's Demand (Green Triangle Points)

Using the table for Alex's demand:

• At a price of $10, Alex demands 32 pairs.
• At a price of $20, Alex demands 20 pairs.
• At a price of $30, Alex demands 12 pairs.
• At a price of $40, Alex demands 4 pairs.
• At a price of $50, Alex demands 0 pairs.

Plot these points with green triangles.

Step 3: Plot Becky's Demand (Purple Diamond Points)

Using the table for Becky's demand:

• At a price of $10, Becky demands 64 pairs.
• At a price of $20, Becky demands 48 pairs.
• At a price of $30, Becky demands 32 pairs.
• At a price of $40, Becky demands 24 pairs.
• At a price of $50, Becky demands 16 pairs.

Plot these points with purple diamonds.

Step 4: Plot the Market Demand (Blue Circle Points)

The market demand is the sum of Alex's and Becky's demands at each price:

• At a price of $10: Alex's demand (32) + Becky's demand (64) = 96 pairs.
• At a price of $20: Alex's demand (20) + Becky's demand (48) = 68 pairs.
• At a price of $30: Alex's demand (12) + Becky's demand (32) = 44 pairs.
• At a price of $40: Alex's demand (4) + Becky's demand (24) = 28 pairs.
• At a price of $50: Alex's demand (0) + Becky's demand (16) = 16 pairs.

Plot these points with blue circles.

Final Graph

The graph will show the three demand curves:

• Alex's demand curve (green triangles) should slope downward from left to right, showing that Alex's demand decreases as the price increases.
• Becky's demand curve (purple diamonds) will also slope downward but be higher than Alex's curve at each price.
• The market demand curve (blue circles) will be the sum of both individual demands and also slope downward.

Tip:

To determine the market demand at any price level, always sum the quantities demanded by all consumers in the market.
