you did not specify the question, but I'm guessing it's "How many people entered the amusement part on average per hour"

Here's how this problem is done:

You first need to figure out the total number of people that entered the park in those seven hours. To do that, you subtract 1278 from 3672, so:

3672-1278=2394

Now, in order to figure out how many people per hour Entered in those 7 hours, you just take the number of total people that entered (2394), and divide by the number of hours (7), so:

2394/7=342. That's your answer!
