<h3>Answer:</h3>
3. R(x) = 25,500 -720x -12x²
<h3>Explanation:</h3>
Starting from 340 tickets, the number of tickets increases by 4 for each unit change in x. Hence, tickets sold will be (340 +4x).
Starting from $75, price per ticket decreases by $3 for each unit change in x. Hence ticket price is (75 -3x).
Revenue from ticket sales is the product of the number of tickets and the price at which they are sold:
... R(x) = (340 +4x)·(75 -3x)
... R(x) = 25,500 -720x -12x² . . . . . matches the 3rd choice
