Simple Interest = p * i * n p is principle and i is interest rate per period and n is the number of periods. A = P(1 + r)n is for compound interest.

What is the simple interest the rate if the interest is 1210 the principle is 15000 and the time is 11 months?

The formula for interest is I = rtP. Then r = I/tP, where t = 11/12. This calculates to a simple interest rate of 8.8 percent.

Suppose that you plan on investing into an account paying simple interest The formula for simple interest is I equals Prt where I is the interest earned on a investment of P dollars at the given rate?

No. I is as described for the stated period.

What is simple interest?

Simple interest does not compound. In other words, If you start off with $500 and get $5 in interest, the $5 you got in interest will not be included when calculating the amount of interest you will get next year. Simple interest can be calculated by the formula i = prt, where i is the amount of money earned from the interest, p is the principle (starting money), r is the rate (as a decimal,) and t is the time in years. Another formula is used to calculated the accumulated amount: A = p(rt + 1), where A is the accumulated amount.
