If a supervisor is salaried at $720 per week and works 8 hours on a Saturday, what is his gross pay for that week?

The supervisor's gross pay for the week is determined by their salary, which is a fixed amount regardless of the number of hours worked, as long as they do not exceed certain thresholds that might trigger overtime considerations. In this case, the supervisor is salaried at $720 per week, which means that regardless of how many hours they work, their pay remains the same.

Since the question specifies that the supervisor is salaried at $720 per week, this amount is their gross pay for that entire week. The additional hours worked on Saturday do not alter the salary unless there is an agreement for overtime pay or unless the supervisory role allows for hourly compensation, which is not indicated in this context.

Therefore, the correct answer is that the gross pay for that week is $720, as this is simply the agreed-upon salary for the week without any additional payments required for the hours worked beyond the normal schedule.
