If I place $300.00 in an account that accumulates 3%, how much is it worth in 30 years?

Answer 1

You don't state if the interest is simple or compounded. For simple interest,

I = PRT (Interest = Principal*Rate*Time)
I = 300 * 0.03 * 30
I = ?

Answer 2

300.x3%=27.00x30 = 810.00

Answer 3

Remember to turn the percentage into a decimal! 3%= 0.03
