Answer:
Option a. Zero.
Step-by-step explanation:
It is given that Sheila worked 38 hours.
Usually there are 8 hours work period for 5 days in a week.
Therefore, working hours are usually 8 × 5 = 40 hours
Work done over 40 hours a week is taken as overtime
But Sheila worked only 38 hours which is less than 40 hours, so she did not earn any overtime.
Therefore, answer would be Option a. Zero.
