@terenzreignz

terenzreignz (terenzreignz):

1.9% of the initial amount :)

OpenStudy (anonymous):

Huh ?

OpenStudy (anonymous):

@terenzreignz

terenzreignz (terenzreignz):

What is 1.9% of 1750 ?

OpenStudy (anonymous):

33.25

OpenStudy (anonymous):

Is that my answer ?

OpenStudy (anonymous):

@terenzreignz

terenzreignz (terenzreignz):

No.

OpenStudy (anonymous):

what do i do next ?

terenzreignz (terenzreignz):

Well, what does 1.9% mean, in decimal?

OpenStudy (anonymous):

0.019

terenzreignz (terenzreignz):

Then multiply that to your principal

OpenStudy (anonymous):

multiply what ? 0.019x33.25

OpenStudy (amistre64):

1.9% tends to be an annual rate

OpenStudy (anonymous):

what do i need to multiply to get my answer ?

OpenStudy (amistre64):

unless stated otherwise, interest rates are annual amounts.

OpenStudy (anonymous):

@terenzreignz @amistre64

OpenStudy (amistre64):

find the interest for the year and divide by 365 is my thought

OpenStudy (amistre64):

\[I=Prt\] \[I=Pr\frac{1}{365}\]

OpenStudy (anonymous):

365*1.9%

OpenStudy (anonymous):

what would my answer be ?

OpenStudy (amistre64):

please ask questions about what has been posted if you do not understand it; as opposed to asking what the answer would be.

OpenStudy (anonymous):

I already asked. What do i need to divide to get my answer . I already did step by step.

terenzreignz (terenzreignz):

I didn't see 'day' Sorry guys

OpenStudy (anonymous):

Its fine

OpenStudy (amistre64):

\[I=Pr\frac{1}{365}\]

OpenStudy (anonymous):

0.00273973

OpenStudy (amistre64):

1750(.019)/365 is not .00273...

OpenStudy (anonymous):

lol all i did was 1/365 not the whole formula. Let me check

OpenStudy (amistre64):

:)

OpenStudy (anonymous):

0.09109589041

OpenStudy (amistre64):

OpenStudy (anonymous):
