OpenStudy (anonymous):

OpenStudy (anonymous):

What grade are you in?

OpenStudy (anonymous):

Consumer Math can be given to anybody grades 9-12. I decided to take this class now in the 12th grade. @jojobuck

Ahhh

OpenStudy (displayerror):

The question tells you exactly how to do the question. It specifically says to multiply the amount by the rate.

OpenStudy (anonymous):

So after adding it up (Or multiplying) it would be 15.00 more right? B.

OpenStudy (displayerror):

The instructions say to multiply the amount by the rate for both rates, so \[2000 \times 5.5 \%\] \[2000 \times 3.25 \%\] Then it tells you to subtract the totals.

OpenStudy (displayerror):

This is the same idea as calculating the amount of tax you have to pay on your purchases or for your meal at a restaurant. If you spend \($5\) on a pair of pants, and the tax rate is \(3 \% \), then the amount of tax you have to pay is \($5 \times 3 \% = $0.15 \)

*facepalm* I only did the first one! I gotta read lol And right that makes sense now! Thanks @DisplayError

OpenStudy (anonymous):

But I got 90,000. What that means?

OpenStudy (displayerror):

Yeah, I typed up a long explanation before I re-read the instructions and saw that it told you how to do the problem, lol. Hopefully that tax example makes sense. It's essentially the same idea with interest rates.

OpenStudy (displayerror):

Remember, you never multiply by percents. You have to convert your percent to a decimal, so \(5.5 \% = 0.055\) and \(3.25 \% = 0.0325 \).

45.00 more! Thanks again @DisplayError ! :D
