Zanny Electronics Corporation uses a standard cost system for the production of its water ski radios. The direct labor standard for each radio is 0.9 hours. The standard direct labor cost per hour is $7.20. During the month of August, Zanny’s water ski radio production used 6,600 direct labor-hours at a total direct labor cost of $48,708. This resulted in production of 6,900 water ski radios for August. What is Zanny’s labor rate variance for August? PLEASE SHOW YOUR WORK BY USING THE HONORLOCK ON-SCREEN CALCULATOR.
