How long will a $9000 investment take to earn $180 interest at an annual interest rate of 8%? @heather040200

OpenStudy (anonymous):

Does it say if the interest is compound or simple?

OpenStudy (anonymous):

it does not sae

OpenStudy (anonymous):

We will go with simple interest rate then: I=p*i*t I=Interest earned p=principal amount i= interest rate plug it in as a decimal t= time in years When you plug in the numbers you get this: 180=9000*.08*t then you just solve for t. Let me know if you need more help. :)
