A 5000-seat theater has tickets for sale at 26 dollars and 40 dollars. How many tickets should be sold at each price for a sellout performance to generate a total revenue of 145,400 dollars?
+36916 5000 seats
x = 26 dollar seats
5000-x = 40 dollar seats
26 x + 40 ( 5000 - x) = 145400 solve for 'x' the # of 26 dollar seats then # of 40 dollar seats = 5000-x
