Respuesta :

Gavin earns more because he earns 20 per hour and eva earns 11.5 per hour.

So Gavin earns 8.50 more than eva.

Hope this helps :)
As we see in the graph Gavin earns 20$ per hour and Eva earns 23$ every two hours.

First, we must figure out how much Eva made in an hour
23 ÷ 2hours = 11.5

Now we subtract to find the difference
20$ (Gavins) - 11.5$ (Evas) = 8.50
Gavins by $8.50 is your answer
