The problem with this question is that it states only "an acount that earns 6.2% interest." Is that annual interest? Is it simple interest? If it is compound interest how often is it compounded?

OpenStudy (anonymous):

I got 488.25

OpenStudy (anonymous):

its monthly, i think.

OpenStudy (anonymous):

It doesn't say, does it?

OpenStudy (anonymous):

OpenStudy (anonymous):

OpenStudy (anonymous):

i used it and got the answer ^ but its not an answer choice.

OpenStudy (anonymous):

488.25

OpenStudy (anonymous):

Did you get an answer?

OpenStudy (mathstudent55):

Before you do anything, did you read the question carefully? If she deposits $1750 in her account, and she earns interest, how can she end up with only $488.25, much less than she started with?

OpenStudy (anonymous):

oh.

OpenStudy (anonymous):

you ADD IT!!!!!!!!

OpenStudy (anonymous):

OMG... Ok. let me see.

OpenStudy (anonymous):

2238.25?!

OpenStudy (mathstudent55):

Is that an answer?

OpenStudy (anonymous):

yes
