Question

a movie theater has been charging $10.00 per person and selling about 500 tickets

Answer 1

they would make about $5,000 

Answer 2

Hey!

Hope this helps...

~~~~~~~~~~~~~~~~~~~~~~~~~~

So we know that 10* 500 = 5000

And what we know (in estimates) is that about 800 extra people came in after the tickets were dropped to $8

We know this because it takes 16/2s to get to 8, and 16*50 = 800

And that 8 * 800 = 8,000

So 6,400 - 5,000 = 1,400

So we know that the theater made $1,400 extra after dropping the tickets to $8...
