20 hours.

Step-by-step explanation:

Javier wants to take a vacation for which estimated cost is = $580

He has already saved money = $260

He makes per hour amount = $16

Let he will work to ensure the amount needed for vacations = x

16x = 320

x =  

x = 20 hours

Javier needs to work for 20 hours.
