Answer:
C. 1,615 seats
Explanation:
To find out how many tickets were sold at the Opera House, you need to calculate 95% of the total number of seats.
95% of 1,700 seats can be found by multiplying 1,700 by 0.95:
1,700 * 0.95 = 1,615
Therefore, the correct answer is C. 1,615 seats were sold at the Opera House.
