a museum opened at 8:00 am. in the first hour 350 people purchased admission tickets. in the 2nd hour 20% more people purchased admission tickets than the first hour. each admission ticket cost 17.50 what was the total amount of money paid for all the tickets purchased purchased in the first 2 hours

Okay, so we already know that 350 people purchased tickets in hour 1:

17.50 (350 + ?) = ?

The question states that in the 2nd hour, there was 20% more people. So basically, we solve for 120% of the people from the 1st hour:

17.50 (350 + 1.2 (350)) = ?

Multiply 1.2 by 350:

17.50 (350 + 420) = ?

Add:

17.50 (770) = ?

Multiply:

17.50 (770) = 13475

$13,475 was the total amount of money.
