How do I translate *"Carla studies the most."* as in the following sentence.

>Maria studies more than Jim but Carla studies the most.


I understand comparatives, so 

> Maria studies more than Jim. is <sub>Maria estudia más que Jim.</sub>

But the only formula that I know for Superlatives, is only in relation to adjectives.

For example
>Mateo es el estudiante **más inteligente**. or Mateo es el **más inteligente.**

but in relation to verbs I'm confused.

For example

>She **sings the best**.

>She **studies the most**.

>She **plays the worse**.

What is more confusing is that Google Translate gives the same Spanish comparative translation for both the English comparative and superlative translation.

Example 

>She studies more.<sub> Ella estudia más.</sub> 

>She studies the most.<sub> Ella estudia más.</sub> 

UPDATE:

What about nouns? What is the superlative formula when dealing with nouns?

How would I translate the following 

> She won the **most money**.
