Verified Answer :

The answer is B. 394.5 

6 X 40 for regular time = 240 

and then if you add in the overtime and holiday time the answer will be more than 240 and the only answer above 240 is B

Answer:

She earned $394.50

Step-by-step explanation:

  1. Hourly income of Mary Stevens in regular hours = $6
  2. Hourly income of Mary Stevens in over-time = \(6\times \dfrac{1}{2}=\$9\)
  3. Hourly income of Mary Stevens in holidays = \(2\times 6=12\$\)

Then, last week she worked  

  1. 40 hours of regular time, earnings = \(40\times 6=\$240\)
  2. \(6\dfrac{1}{2}\) hours of overtime, earnings = \(6\dfrac{1}{2}\times 9=\$58.5\)
  3. 8 hours of holiday time, earnings = \(8\times 12=\$96\)

Hence, her total earnings = 240+58.5+96 = $394.50
