How long would it take to earn 16,000 in interest on a principle of 12,500 in 4 years what is the interest rate on your account

Such a confusingly worded question.

isnt it?

You need more information. You need to know the interest RATE. The formula for simple interest is I = P*r*t, where I is the interest you've gained, P is the principle, r is the rate, and t is the time. If you know any 3 of those things, it's simple to find the 4th.

Your problem only gives 2 of the 4 variables, so I can't solve it.
