After the 4thyear,$200 is added to the account. Use the expression for to write a new expression that represents how much is in the account after 5 years. 

Let’s break this down step by step.

Assume the account has some amount of money $ P_4 $ at the end of the 4th year. After this year, $200 is added to the account, so the balance at the end of the 5th year can be expressed as:

\[
P_5 = P_4 + 200
\]

This expression represents the amount of money in the account after 5 years, where $ P_4 $ is the amount at the end of the 4th year, and $200 is the amount added at the start of the 5th year.

### Questions for further learning:
1. What if the account earns interest? How would you adjust the expression?
2. How would the expression change if an additional amount was added each year?
3. If the $200 was added at the beginning of the 5th year instead of after the 4th year, would the outcome change?
4. How would the expression change if instead of $200, a percentage increase was applied?
5. What formula would you use if you wanted to calculate interest along with this additional amount?

**Tip:** Always clarify if interest or any other form of growth is being added when working with account balances over time.

After the 4th year, $200 is added to the account. Use the expression for to write a new expression that represents how much is in the account after 5 years.
