Arestaurant worker server earns a base salary of $6 per hour plus tips. if he averages $12 per hour in tips, how many hours must he work to earn a total of $333?

18.5 hours

To solve this problem, you first need to figure out the average amount of money per hour the worker earns.

That would be the base salary plus the average tips per hour. So

$6 + $12 = $18

Then to figure out how many hours the worker needs to work, divide the goal by the hourly earnings. So

$333 / $18 = 18.5 hours.

Therefore on average, it will take 18.5 hours to earn $333, assuming a base salary of $6/hour and an average of $12 in tips per hour.
