Question

Mary Stevens earns $6 an hour at her job and is entitled to time-and-a-half for overtime and double time on holidays. Last week she worked 40 hours of regular time, 61/2 hours of overtime, and 8 hours of holiday time. How much did she earn? A. $140.00 B. $394.50 C. $190.75 D. $74.37

Answer 1

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 2

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
