Serena earns 7.50 more than Gabe.

Step-by-step explanation:

Hi, the missing part of the question is how much does Gabe earn per hour.

Gabe earns 13.50  

Since Serena earns $21 per hour  

We simply have to subtract the amount that Gabe earns, to the amount that Serena earns.  

Mathematically speaking  

21-13.50 = 7.5  

Serena earns 7.50 more than Gabe.
