All employees at FreeMedicalOrgans.com are paid biweekly, i.e., every two weeks. An hourly employee's biweekly gross pay (denoted by variable grossPay) is calculated as the number of hours he or she worked (denoted by variable hrsWorked) during the pay period multiplied by his or her hourly pay rate (denoted by variable payRate). In addition, hourly workers are eligible for overtime pay if their hours worked exceeds 80 hours during the two week pay period. The overtime pay rate is one-and-a-half times the usual pay rate.
