Question 464663: This is my homework problem: "$500 was originally invested into an account that earns simple interest. after 3 years the account had a total worth of $650. Write an equation to model the situation and then Find the interest rate."
I have a partial equation of I = (500)(r)(3)
Or 650 + 500 = R
My biggest issues is that I honestly do not understand at all what I'm doing with the percent and interest equations. I don't know which one is correct.
I Do know that over the three years $150 came into the account at a rate of $50 a year...the problem is I don't know how to convert that knowledge into a percentage.
Thank you so much for solving this problem for me.
