Pls- ! (this is linear programming)- the amphitheater has two types of tickets available, reserved seats and lawn seats. the maximum capacity of the venue is 20,000 people, however, they must sell at least 5,000 tickets for a concert to be held. as a additional constraint the number of lawn seats can't exceed the number of reserved seats. if reserved seats profit 65$ each and lawn tickets profit 40$ each, how many of each must they sell to maximize their profits.
