Answer:
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
