Final answer:
When Rob worked a holiday and was paid time and a half, he received the standard overtime rate that is 1.5 times his hourly rate.
Step-by-step explanation:
When Rob worked a holiday and was paid time and a half, he received the standard overtime rate, which is 1.5 times his regular hourly rate.
For example, if Rob's regular hourly rate is $10, his overtime rate would be $10 x 1.5 = $15 per hour for the hours worked on the holiday.
Therefore, the answer is C. Rob received the standard overtime rate that is 1.5 times his hourly rate.
