Answer:
- Sammy would have to work 27 hours time and a have pay to make more than his 40 hour work week.
Solution:
- 21 x 40 gives us $840 which is his base pay for the week.
- ⇒ 1.5 x 21 would give us 31.5 which is his time and a half pay
- ⇒ If you mess around with the hours (31.5 x Sammy's work hours) you will see at 27 hours at time and a half pay, Sammy exceeds base weekly pay.
Thus you get your answer of 27 hours!
Enjoy your day! - Zac
