Lance makes $11.35 an hour and earns time and a half pay for every hour over 40. If Lance worked 47 hours this week, about how much will his paycheck be? Round to the hundredth place.

- $546.24
- $454
- $573.18
- $521.37

Answer: **$573.18 is correct because $11.35 an hour x 40 hours a week equals $454. Time and a half pay for Lance would be $17.025 and you figure that out by multiplying $11.35 an hour by 1.5. Then multiply $17.025 times 7 overtime hours to get $119.175. Lastly, add $454 and $119.175 and you will get $573.175. Rounded to the hundredth place would be $573.18.
