You invest an initial $1,000 in an account that has an annual interest rate of 2.5%, compounded annually. How much money will you have in the account after 6 years? Round your answer to the nearest whole number.

So the formula would be A=Pe^rt, right? Plug in 1000 for the principal, 2.5% in decimal form for r, and I believe you plug in the equivalent of 6years in months. Does it tell you in the lessons to do that? Then put the equation into a calculator.

The formula for annual compound interest is \[A=P(1+r\space )^{t}\]

hero (hero):

In this case P = 1000 t = 6 r = .025

OpenStudy (anonymous):

so the equation would be A=1000(1+.025)^6

hero (hero):

Correct

OpenStudy (anonymous):

my answer would be 1,159.70

OpenStudy (anonymous):

rounded though it would be $1,160

Oh, I'm sorry I was thinking of continuous compounding. D:
