Mariana [72]

Answer:

<u>96 percent</u> of the seats were the tickets sold.

Step-by-step explanation:

Given:

Atlantic auditorium has 850 seats. Tickets were sold for 816 of the seats.

Now, to find percent of the seats of the tickets sold.

Total number of seats = 850.

Tickets sold for the total seats = 816.

So, to find the percent of the seats of the tickets sold:

\frac{816}{850}\times 100

=0.96\times 100

=96\%.

Therefore, 96 percent of the seats were the tickets sold.
