In two weeks, 575 hamburgers were sold in a college cafeteria. At this rate, how many hamburgers would we expect the cafeteria to sell in 3 months?

You could use a proportion.

hamburgers/weeks = hamburgers/weeks

You know that there were 575 hamburgers sold in 2 weeks:

575 / 2 = hamburgers / weeks

You're looking for the number of hamburgers sold in 3 months. Let x = the number of hamburgers sold in that time period. How many weeks would there be in 3 months? Put that value in for "weeks" in the second fraction. Then, solve the proportion. If you're having trouble with this problem, please repost, showing your work, so we can see how best to help you.

What assumptions are you supposed to make regarding the relationship between "two weeks" and "three months"? (Since there aren't four weeks to one month, obviously you cannot use that comparison. Are you supposed to assume 30 days? Four and a third weeks? Or something else?)

When you reply, please include a clear listing of everything you have tried so far. Thank you!
