your question?

OpenStudy (anonymous):

An initial amount of money is placed in an account at an interest rate of 2% per year, compounded continuously. After six years, there is $3348.67 in the account. Find the initial amount placed in the account. Round your answer to the nearest cent.

OpenStudy (anonymous):

ok so 2% is 2/100 which equals .02 correct

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

so after 6 years that account has 12% more than it had 6yrs ago

OpenStudy (anonymous):

so how do i get the amount

OpenStudy (anonymous):

isnt there an equation for this

OpenStudy (anonymous):

nope :/

OpenStudy (anonymous):

@dan815

OpenStudy (anonymous):

i knew it there is an equation which is A=Pe^rt

OpenStudy (anonymous):

A is final amount r is interest rate and t is time

OpenStudy (anonymous):

so you manipulate the problem to get P=A/e^rt which becomes P=3348.67/e^.02*6

OpenStudy (anonymous):

then just solve for p and you'll have your answer

I got 2970 :/ but I'll check my answer thanks
