Final answer:
Rob Farinelli's overtime earnings for the week are $387.75.
Step-by-step explanation:
To calculate Rob Farinelli's overtime earnings for the week, we need to determine the regular rate of pay and the overtime rate. The regular rate of pay is calculated by dividing the monthly salary by the number of hours worked in a month. In this case, the regular rate of pay is $2756 / (4 weeks * 40 hours) = $17.23 per hour.
The overtime rate is one and a half times the regular rate of pay. So the overtime rate is $17.23 * 1.5 = $25.85 per hour.
Rob worked 55 hours in one week, which includes 15 hours of overtime (55 - 40). Therefore, his overtime earnings for the week would be 15 * $25.85 = $387.75.
