Problema Solution

Person A deposits ​$2800 in an account that pays 9​% interest compounded once a year.In their account after one​ year? How much​ more?

Answer provided by our tutors

I am assuming you need to find the feature value and the interest.

Let

P = $2800 the principle (the investment)

i = 9% or 0.09 the annual rate as a decimal

t = 1 years

A = the future value

I = the interest

The formula for the future value is:

A = P(1 + i)^t

Plug the values into the formula:

A = 2800(1 + 0.09)^1

A = $3052

I = A - P

I = 3052 - 2800

I = $252

After 1 year there will be $3052 on the account, $232 more than the deposit.
