Question

At a certain movie theater, there are 500 seats. If 40% of the seats have been sold in advance and the day before the premiere 100 seats are sold, how many seats must be sold on the day of the movie for the theater to be sold out? Write an equation.

Answer 1

To find out how many seats must be sold on the day of the movie for the theater to be sold out, calculate the remaining seats after the advance sales and the seats sold the day before the premiere. The equation is: Total seats - seats sold in advance - seats sold the day before the premiere.

Step-by-step explanation:

To find out how many seats must be sold on the day of the movie for the theater to be sold out, we need to calculate the remaining seats after the advance sales and the seats sold the day before the premiere.

Step 1: Calculate the number of seats sold in advance:

• 40% of 500 seats = 0.4 * 500 = 200 seats

Step 2: Calculate the number of seats sold the day before the premiere:

• 100 seats

Step 3: Calculate the remaining seats:

• Total seats - seats sold in advance - seats sold the day before the premiere = 500 - 200 - 100 = 200 seats

So, 200 seats must be sold on the day of the movie for the theater to be sold out.
