I need help finding the answer to this: Nathan opens a new savings account and makes an initial deposit of $400. If the account earns 2% annual interest, how much interest will he earn in 9 months?

He will earn $6 in interest in 9 months.

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

After t years, the total amount of money is:

Initial deposit of $400.

This means that

2% annual interest

This means that

How much interest will he earn in 9 months?

An year has 12 months, this means that

This is E. So

He will earn $6 in interest in 9 months.
