Ahealthy fast-casual restaurant that offers only vegetarian and vegan meals insists on portraying organic ingredients in its advertisements, charges a higher price for its meals, and has a rigorous quality control process to insure the cleanliness of its facilities. what strategy is the manufacturer using to deliver superior value to customers?

The strategy that they use is signaling value by targeting sophisticated buyers

This type of strategy could only work if the target market has specific preferences.
Even though the number of potential consumers for this market tend to be considerably small compared to another market, but the customers that obtained through this strategy tend to show higher level of loyalty.

$2,500

Explanation:

P = 12.5

TR = P × Q

     = $12.5 × 1,000 units

      = 12,500

TC = ATC × Q

     = $10 × 1,000 units

     = 10,000

Profit = TR - TC  

         = $12,500 - $10,000

         = +2,500

Profit is positive, but for perfectly competitive markets there will be no [economic] profits at all in the long-run.

So, in this markets new firms will enter market attracted by profits thus increasing market supply and reducing price to 10.
