A play was held in an auditorium and its ticket costs $10. An auditorium has 20 rows and each row has 10 seats. If only 3/4 of the seats were sold, how much was earned from the play?
How many seats are there? ** There are 20 x 10 = <<20*10=200>>200 seats in the auditorium.
How many seats were sold? ** Only 200 x 3/4 = <<200*3/4=150>>150 seats were sold.
How much was earned from the play? ** Hence, the earnings from the play is $10 x 150 = $<<10*150=1500>>1500.
