I redid the math for number 4 and I think the answer is actually B.

OpenStudy (dinorap1):

@LoveIt Oh hi I remember you

OpenStudy (anonymous):

Hi!! 2nd one seems correct: A = P(1 + rt); R = r * 100 Where: A = Total Accrued Amount (principal + interest) P = Principal Amount I = Interest Amount r = Rate of Interest per year in decimal; r = R/100 t = Time Period involved in months or years 1st one might be D: Principal is the amount of money borrowed or invested. now looking at 3rd one..

OpenStudy (dinorap1):

Is that the right formula? The one I was given was I=Prt

OpenStudy (dinorap1):

Interest=Principal*rate*time

OpenStudy (anonymous):

Hm, maybe it's a more complicated formula; just go with yours.

OpenStudy (dinorap1):

Yep, it's just a more complicated one than the one I have.

OpenStudy (dinorap1):

I'm pretty sure number 1 is correct: Principal is the original amount invested (A)

OpenStudy (anonymous):

For the next two I'm kind of unsure ;-; @Directrix @KendrickLamar2014

OpenStudy (anonymous):

Sorry!!!

OpenStudy (dinorap1):

Here's what I did for number 3: I=4000*.05*3/12

OpenStudy (dinorap1):

Does that make sense?

OpenStudy (dinorap1):

The .05 is 5% converted to a decimal and the 3/12 is 3 months out of 12, so only .25 of the year.

OpenStudy (anonymous):

Oh, is it not I=2000*.04*3 /12? Try to ask other ppl just to make sure you're correct though Plus, you're more experienced at this than I am

OpenStudy (dinorap1):

Oops I was looking at the wrong numbers. I was looking at number 4. Number 3: I=2000*.04*3/12=$20

@Directrix Can I just open up a new question and tag you in it so you're not confused?
