Each admission ticket cost $17.50. What was the total amount of money paid for all the tickets purchased in the first two hours? Show your work.

First hour = 350 people

Second hour = 20% more people 

20% x 350 = 0.2 x 350 = 70

350 + 70 = 420

Second hour = 420 people

Total number of people in the first 2 hours = 350 + 420 = 770

Total amount paid = 770 x $17.50 = $13475
