Norva, Inc. has budgeted the following costs for the manufacture of XP1, a component used in several of its products. It plans to produce 4.500 units of XP1 in the upcoming year. To do this Norva has budgeted Direct Materials of 13,500 ounces at $0,40 per ounce and Budgeted Direct labor of 1,500 hours at $35.00 per hour. For the year Norva actually manufactured 4.800 units of XP1 using 14,500 ounces of materials at an average cost of $0.44 per ounce and 1,550 hours of direct labor at an average cost of $37.00 per hour. What is the direct labor efficiency variance? (Note this could be a positive number indicating an unfavorable variance or a negative number indicating a favorable variance. Do not include a dollar sign and do not add a plus sign to positive numbers as Blackboard will mark the answer as incorrect.)
