A museum opened at 8:00 am. In the first hour, 350 people purchased admissions tickets. In the second hour, 20 percent more people purchased admission tickets than in the first hour. Each admission ticket cost 17.50, what's the total amount of money paid for all the tickets purchased in he first 2 hours.

The museum made $13,475 on tickets in the first two hours of opening.

Step-by-step explanation:

First, identify what you know:

1) In the first hour, the museum sold 350 tickets.

2) In the second hour, 20% more people purchased admission tickets than in the first hour.

3) Each admission ticket costs $17.50

So, first, what is 20% of 350?

20% x 350 = 70

So, 70 more people bought tickets in the second hour than the first hour!

350 + 70 = 420 people bought tickets in the second hour

So, add the tickets for both hours!

350 + 420 = 770

Now multiple the number of tickets sold by the cost for one ticket

770 tickets sold x $17.50 = $13,475
