These two expression are equivalent when x = 3
2x+1 and 5−7x
True or False

I’m pretty sure the answer is true

First we have to determine how many people fir in each section. 
Since these sections are evenly distributed, each section has a third of the capacity, thus= 15,000/3 = 5000 persons per section.

Now we determine revenue by section by multiplying times the ticket price.

5,000 * $10.00 = $50,000
5,000 * $12.50 = $62,500
5,000 * $15.00 = $75,000

We add up the totals for $187,500 and that's the answer!
