Give the step-by-step reasoning process and then the final answer. 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?
User
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.
The final answer: 1500.
