Answer:
The restaurant should set the price of the sandwiches at $ 5.75 to maximize its profit, which would reach $ 1,983.75.
Explanation:
Given that a restaurant sells 330 sandwiches each day for $ 6 each, and that for each $ 0.25 decrease in price, the restaurant sells about 15 more sandwiches, to determine how much the restaurant should change to maximize daily revenue and what is the maximum daily revenue should perform the following calculations:
330 x 6 = 1980
345 x 5.75 = 1983.75
360 x 5.5 = 1980
Thus, the restaurant should set the price of the sandwiches at $ 5.75 to maximize its profit, which would reach $ 1,983.75.
