Much like the previous question, the units can be used to address this problem. Setting up a fraction for dollars per hour yields 168 dollars/12hours. After simplifying, the answer is 14 dollars per hour.
confidence rating #$&*: 3
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Given Solution: $168 earned in 12 hours implies that $168 / 12 = $14 were made per hour, so the rate is $14 / hour.
