Quizplus · Accepted Answer

To find the market supply at $7.50, we need to calculate the change in quantity supplied for each brand and add them together.

For Duracell: 
Change in quantity supplied = 12,000 - 10,000 = 2,000

For Energizer: 
Change in quantity supplied = 16,000 - 15,000 = 1,000

Total change in quantity supplied = 2,000 + 1,000 = 3,000

Therefore, the market supply at $7.50 is the sum of the new quantities supplied for Duracell and Energizer: 
Market supply = 12,000 + 16,000 = 28,000

Thus, the answer is D (28,000).
