Algebra practice question
A worker is paid $12 per hour for the first 40 hours in a week and $18 per hour for each hour beyond 40. In one week the worker earned $624. How many hours did the worker work that week?
Answer: 48
480 + 18h = 624 gives h = 8 overtime hours, so 40 + 8 = 48.

- If you answered 52
- 52 divides 624 by 12, ignoring the overtime rate.
- If you answered 34.67
- 34.67 divides 624 by 18.
