OpenStudy (zappy620):
\[A=1000e ^{8*1/4*5}\]
OpenStudy (zappy620):
So far that's what i got. The exponents are 8*1/4*5
OpenStudy (zappy620):
actually its 8.25*5
OpenStudy (zappy620):
\[A=1000e ^{8.25*5}\]

this is the general formul\[p(1+i/n)^{n}\]
OpenStudy (zappy620):
i got that so far but it comes out to be a really huge number compared to the books answer
OpenStudy (zappy620):
hm let me plug it in btw the books answer is $1510.59
OpenStudy (zappy620):

OpenStudy (zappy620):
then what's i?
OpenStudy (anonymous):
i is the rate
OpenStudy (zappy620):
ah ok
OpenStudy (zappy620):
so the last part of the equation is i/r^r?
OpenStudy (zappy620):
I was given these equations from the book

OpenStudy (zappy620):

you had to convert 8.25 into a decimal
OpenStudy (zappy620):
.0825 * 5 = 0.4125
OpenStudy (zappy620):
2.71828^0.4125=1.51058... then you mulitply it by a 1000 to get $15109.59

atleast u understnd it
