a new expression B(x) that represents how much is in the account after 5 years.

Answer 1

The expression of the money in the account after 5 years will be  

B(x) = A(x) + $200

According to the question,

After 5 years $200 is added to the account.

So let A(x) represents the initial amount present in the account.

Let B(x) represent the account’s money after 5 years.

So according to the statement, the equation will become,

Money after 5 years in the account = Initial amount in the account + $200

Which will be numerically stated as below,

         B(x) = A(x) + $200

This clearly shows the money in the account after 5 years when $200 is added to the account.
