You can put this solution on YOUR website!
Rules for posting:
1. Ask an actual question. A question is a series of words that form a sentence where it is appropriate to append a question mark,
(i.e., one of these things: "?") to the end of the sentence.
Please look up the definition if you are still unclear on the concept.
On this website, such a question should relate to some area of mathematics.
2. If you post a problem for which you want a solution, make sure you make it clear what it is about the problem that is giving you difficulty.
3. Show all of the work, successful or not, done or attempted in the solution of the problem. In other words, demonstrate that you are trying to learn something about mathematics as opposed to just trying to get someone else to do your thinking for you.
4. If following these instructions is too much work for you, then helping you is too much work for us.

You can put this solution on YOUR website! this looks like a simple interest equation.
that equation is:
A = p + i.
A is the total value of the investment at the end of the investment period.
p is the principal, which is the value of the investment at the beginning of the investment period.
i is the interest that was earned on the principal during the investment period.
the value of i has its own equation, which is:
i = p * r * t
i is the interest earned on the investment during the investment period.
p is the principal which is the investment at the beginning of the investment period.
r is the interest rate per time period.
t is the number of time periods.
for example:
you are given that:
the initial investment is 1000 dollars.
the interest rate is 5% per year.
the number of years invested is 15 years.
you are asked to find the value of the investment at the end of the investment period.
the formula is A = p + i
since i = p * r * t, then:
i = 1000 * .05 * 15 = 750
A = p + i becomes A = 1000 + 750 = 1750
to find i, you had to use the i formula.
note that the rate was used and not the percent rate.
rate = percent rate / 100.
