How can you formulate the formula f p 1 r t?

To find the interest rate (r) in the formula a=p(1+r)t , you need to know the values of a (amount), p (principal) and t (time). You would take a and divide it by p. You will then take that result and take the t root of it. You then subtract that answer by 1 to get your interest rate in decimal form.

What are the steps in solving mathematical equations?

A General Rule for Solving Equations

What does the formula A P 1 r/t mean?

Yearly Compound Interest Formula If you put P dollars in a savings account with an annual interest rate r , and the interest is compounded yearly, then the amount A you have after t years is given by the formula: A=P(1+r)t. Example: Suppose you invest $4000 at 7% interest, compounded yearly.

What is r in interest?
