To determine the additional amount Malia needs to save to buy the hamster cage, we can express the situation using the equation:

\[
18.50 + s = 30
\]

In this equation:
- \( 18.50 \) is the amount Malia has saved.
- \( s \) is the additional amount she needs to save.
- \( 30 \) is the total cost of the hamster cage.

From the options you provided, the correct equation for this scenario is:

\[
18 \, \text{dollars and} \, 50 \, \text{cents} + s = 30 \, \text{dollars}
\]

So the answer is:

**18 dollars and 50 cents + s = 30 dollars**.
