Deluxe Fender, which uses a standard cost system, manufactured $20\mathrm{.}000$ boat fenders during $2024,$ using $142\mathrm{.}000$ square feet of extruded vinyl purchased at $$1\mathrm{.}40$ per square foot. Production required $440$ direct labor hours that cost $$15\mathrm{.}00$ per hour. The direct materials standard was seven square feet of vinyl per fender, at a standard cost of $$1\mathrm{.}45$ per square foot. The labor standard was $0\mathrm{.}026$ direct labor hour per fender, at a standard cost of $$14\mathrm{.}00$ per hour.

Compute the cost and etticiency variances for direct materials and direct labor.

Does the pattern of variances suggest Deluxe Fender's managers have been making trade$-$offs? Explain
