Answer:
10% of the 250 seats are empty!
Explanation:
First, identify what you know:
1) There are a total of 250 seats in the theater.
2) 225 of those seats were already sold.
Firstly, let's calculate the percentage of seats that were sold! Simply divide the number of seats sold by the total number of seats!
225/250 = 0.9 OR 90%
If 90% of the seats have been sold, how many are empty?
100% - 90% = 10%
10% of the seats in the theater are empty!
