A full-time engineer works eight hours a day, five days a week and is allowed four weeks of paid time off per year. Approximately how many hours does the engineer work in one year?

• A. 2080 hours
• B. 2000 hours
• C. 1920 hours
• D. 2160 hours

Answer: (B)

You’re figuring how many hours are actually worked in a year when there’s paid time off. Start with the weekly schedule: 8 hours per day times 5 days a week equals 40 hours each week. If there were no time off, yearly hours would be 40 × 52 = 2080.

Four weeks of paid time off means you don’t work those weeks, so subtract 4 × 40 = 160 hours. So 2080 − 160 = 1920 hours worked per year. The approximate annual hours worked is 1920.
