Answer:
\(1.003P\)
Step-by-step explanation:
We are asked to write an algebraic expression for the given word phrase.
The principal amount P originally deposited in a bank account plus 0.3% interest.
The interest would be 0.3% of P.
\(\text{Interest}=\frac{0.3}{100}*P=0.003P\)
The total amount in the account would be principal plus interest.
\(P+0.003P\)
\(1.003P\)
Therefore, our required expression is \(1.003P\).
