Matthews Fender, which uses a standard cost system, manufactured 20 comma 000 boat fenders during 2018, using 143 comma 000 square feet of extruded vinyl purchased at $ 1.30 per square foot. Production required 400 direct labor hours that cost $ 16.00 per hour. The direct materials standard was seven square feet of vinyl per fender, at a standard cost of $ 1.35 per square foot. The labor standard was 0.028 direct labor hour per fender, at a standard cost of $ 15.00 per hour. Complete the costs and efficiency variances for Direct materials and direct labor. Does the pattern of variances suggest Pro Fender's managers have been making trade-offs? Explain.
