OpenStudy (mathstudent55):

The population of Pinecrest is 18,000. The population of Lakewwod is a fraction of that population. The fraction is 21/25 21/25 is close to 20/25. 20/25 reduces to 4/5. The population of Lakewood is just a little more than 4/5 the population of Pinecrest. 4/5 is the same as 80%. Of all the choices, which one seems like it can be approximately 80% or 4/5 of 18,000?

OpenStudy (gabebae):

never mind then

OpenStudy (gabebae):

I would pick B

OpenStudy (mathstudent55):

Now look at the choices to decide. A. 21,149: this is even more than Pinecrest. 80% of 18,000 cannot possibly be more than 18,000, so choice A is out. B. 15,120: 4/5 or 80% of 18,000 could be somewhere near this number, so this number seems reasonable, C. 741: 10% of 18,000 is 1,800. 741 is much less that 1800, so it's much less that 10% of 18,000, so it can't be, since we need approximately 80% of 18,000. D. 721: same explanation as for C. Since the only reasonable answer is B, that's the correct answer.
