Solution Steps

Step 1: Calculate the total quantity demanded by the four consumers at \$7 per bulb

At a price of \$7, the quantities demanded by the four consumers are:

  • Gloria: 6 bulbs
  • Michele: 1 bulb
  • Amy: 11 bulbs
  • Annie: 6 bulbs

The total quantity demanded by the four consumers is: \[ 6 + 1 + 11 + 6 = 24 \text{ bulbs} \]

Step 2: Calculate the average quantity demanded per consumer at \$7 per bulb

The average quantity demanded per consumer is: \[ \frac{24}{4} = 6 \text{ bulbs per consumer} \]

Step 3: Project the total market quantity demanded at \$7 per bulb

The total market consists of 40,000 consumers. The projected total market quantity demanded is: \[ 6 \text{ bulbs/consumer} \times 40,000 \text{ consumers} = 240,000 \text{ bulbs} \]

Final Answer

\(\boxed{240,000}\)
