Answer:
To maximize profits, the deli should charge each sandwich at $ 3.9.
Explanation:
Given that a deli sells 720 sandwiches per day at $ 6 each, and a market survey shows that for every $ 0.10 reduction in price, 40 more sandwiches could be sold, to determine how much should the deli harge in order to maximize revenue, the following should be done calculation:
720 x 6 = 4320
760 x 5.9 = 4484
800 x 5.8 = 4640
840 x 5.7 = 4788
880 x 5.6 = 4928
920 x 5.5 = 5060
960 x 5.4 = 5184
1000 x 5.3 = 5300
1040 x 5.2 = 5408
1080 x 5.1 = 5508
1120 x 5 = 5600
1160 x 4.9 = 5684
1360 x 4.4 = 5984
1400 x 4.3 = 6020
1600 x 3.8 = 6080
1560 x 3.9 = 6084
1520 x 4 = 6080
Therefore, to maximize profits, the deli should charge each sandwich at $ 3.9.
