The insured has a guaranteed wage agreement. Employees are paid based on a 45-hour workweek. Any employee working 45 hours or less in a week is guaranteed to earn $665 (calculated as 40 hours at the normal rate of $14.00 per hour and 5 hours at $21.00 per hour). Any hours worked in excess of the guaranteed wage agreement are paid at one-and-a-half times the regular hourly rate. If an employee worked 51 hours in one week, what is the amount to be included in the premium base?
