conversations.value: 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?
  Give me a clear explanation.

conversations.value: There are 20 x 10 = 200 seats in the auditorium.
  Only 200 x 3/4 = 150 seats were sold.
  Hence, the earnings from the play is $10 x 150 = $1500.
