the theaters sell tickets for a concert. tickets for the lower level are $35 each and tickets for the upper level are $25 each. the theater sold 350 tickets for $10,250. how many tickets were sold in each section

9514 1404 393

Step-by-step explanation:

Let x represent the number of lower-level tickets sold. Then the total revenue is ...

  35x +25(350-x) = 10250

  10x +8750 = 10250 . . . simplify

  10x = 1500 . . . . . . . . . subtract 8750

  x = 150 . . . . . . . . . . . lower-level tickets sold

  350-x = 200 . . . . . upper level tickets sold

There were 150 tickets sold for the lower level, and 200 sold for the upper level.
