Question

You work for 4 hours on Saturday and 8 hours on Sunday. You also receive a $50 bonus. You earn $164. How much did you earn per hour? 164-50=

Answer 1

4h + 8 + 50 = 164; $9.50

Answer 2

Assuming you mean $164 total including bonus, and you want to exclude the bonus from your hourly wage.

Money/hour = Total money/total time spent.
Total time = 4 hours on Saturday + 8 hours on sunday = 12 hours
Total money = $164 total - $50 bonus = $114
Money/hour = $114/12 hours = $9.50/hour
If you want to include the bonus, change $114 to $164.
