Solution Steps

Step 1: Individual Demand Curves

The individual demand curves are plotted by matching the quantity of gallons consumed per week (x-axis) with the marginal benefit (price) they receive (y-axis). For example, Ang's demand curve will have points at (1, $7), (2, $5), (3, $3), and (4, $1). Similarly, for Tony: (1, $4), (2, $3), (3, $2), (4, $1). And for Gianna: (1, $8), (2, $6), (3, $4), and (4, $2).

Step 2: Market Demand Curve at Price $7

At a price of $7 or higher, only Ang would buy 1 gallon. So, the market demand at $7 is 1 gallon.

Step 3: Market Demand Curve at Price $6

At a price of $6, Ang would buy 2 gallons (since her marginal benefit at 2 gallons is $5, which is less than $6), and Gianna would buy 1 gallon. This gives a total market demand of 3 gallons at a price of $6.

Final Answer

Individual curves are plotted based on the table. The market demand curve starts at (1, $7), then goes to (3, $6)... The final plotted market demand curve would have points at (1,$7), (3,$6), (6,$5), (7,$4), (8,$3), (10,$2) and (12,$1).
