Question

A museum opened at 8:00 a.m. In the first hour, 350 people purchased admission tickets. In the second hour, 20% more people purchased admission tickets than in the first hour. Each admission ticket cost $17.50.
What was the total amount of money paid for all the tickets purchased in the first two hours?

Answer 1

$13,475 because
300+20% gives you a 420
420+300=720 total sold tickets in the 1st 2 hours
Multiply 720 times the cost of each ticket gives you the total earned amount
