A project required 117,900 actual carpenter work hours, of which 15% were performed on an overtime basis. The carpenter's base pay was $27.50 per hour, and the total union fringes were $6.27 per hour. Overtime work was paid at double time. 

How much additional labor expense would the contractor employer incur if the union agreement called for payment of union fringes on an hours-paid basis rather than on an hours- worked basis.
