Real World Math Formula: I = PRTInterest = Principal *Rate*Time

If you invest $4000 at a bank that pays 2.5% interest for 3 years, how much money will you have?

I = 4000*.025*3I = $300

What is the interest rate if I earned $150 on my $500 investment after 10 years?

150=500*r*10 so... r = .03 or 3%
