Dont pass this question by! please help me!

OpenStudy (amistre64):

that didnt live up to the hype :/

OpenStudy (anonymous):

A deposit of $4,000 at 9.5% for 270 days

OpenStudy (anonymous):

Simple

OpenStudy (amistre64):

i belive simple interest uses a 360 day year, is that correct?

OpenStudy (amistre64):

if not, then using a 365 day year is just a easy

OpenStudy (anonymous):

oh i thought it was 365

OpenStudy (amistre64):

[I = Prt, they give you P and r, t = 270/(days in year)

OpenStudy (anonymous):

These are my options : 280.00, 275.00, 285.00

OpenStudy (anonymous):

Yes thats how its done but I didn't come up with any of these answers

OpenStudy (amistre64):

i get one of them

OpenStudy (amistre64):

whats your principal? remember to use a decimal version of the rate: .095, and use 360 as days

OpenStudy (anonymous):

I did 4000 X .095 X 0.74

OpenStudy (amistre64):

i used .75

OpenStudy (anonymous):

OHH so I am supposed to use 360? not 365?

OpenStudy (amistre64):

360 is the assumption with simple interest, unless stated otherwise

OpenStudy (anonymous):

No in the example is just uses 365

OpenStudy (anonymous):

Thanks

OpenStudy (amistre64):

the author of your material may have their own interpretation, if they want you to use 365 days, then 281 is the colosest

OpenStudy (anonymous):

okay thank you:)

OpenStudy (amistre64):

hmm, i recall that the 360 is a result of the assumption that there are 12 months with equal number of days (30). 12*30 = 360 270/30 = 9 months
