OpenStudy (compassionate):

Do you know the formula for interest?

OpenStudy (anonymous):

no

OpenStudy (compassionate):

When you know the principal amount, the rate and the time. The amount of interest can be calculated by using the formula:I = Prt

OpenStudy (compassionate):

I = (80,000) x (0.05)(9)

OpenStudy (anonymous):

36000?

OpenStudy (compassionate):

Oh, it says compound interest. M = P( 1 + i )^n Let's say that I have $1000.00 to invest for 3 years at rate of 5% compound interest. M = 1000 (1 + 0.05)^3 = $1157.62. You can see that my $1000.00 is worth $1157.62.

OpenStudy (anonymous):

so 1157.2=62 is the final answer? o.0

OpenStudy (anonymous):

1157.62*

OpenStudy (compassionate):

No. I was giving you an example. To get your answer solve this. M = 80,000(1 + 0.05)^9 = ?

@Compassionate ?

OpenStudy (compassionate):

Yes. Now round to the tenth. Also, I don't answer notifications. Next time don't tag me, just send me a few messages and get on the chat. I also recommend leaving a note on my profile to grab my attention.
