Can someone explain how to do #5 for me? Answer is suppose to be $1510.59

OpenStudy (zappy620):

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):

\[A=1000e ^{8.25*5}\]

OpenStudy (anonymous):

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):

whats i in the equation and is that an r?

OpenStudy (anonymous):

yes

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):

I think i'm suppose to use the first one considering the 2nd equation was used in the last section

OpenStudy (zappy620):

Neither of them are making any sense :(

OpenStudy (anonymous):

i am trying them if i get the answer i will tell u

OpenStudy (zappy620):

thank you <3

OpenStudy (zappy620):

I GOT IT

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

OpenStudy (anonymous):

atleast u understnd it
