Copland Components manufactures an electronic device for vehicle manufacturing. The current standard cost sheet for a device follows:

Direct materials, $?$ ounces at $$2\mathrm{.}80$ per ounce $ $?$ per device

Direct labor, $0\mathrm{.}40$ hours at $?$ per hour $?$ per device

Overhead, $0\mathrm{.}40$ hours at $?$ per hour $?$ per device

Total costs $ $30$ per device

Assume that the following data appeared in Copland$$s records at the end of the past month:

Actual production $96,520$ units

Actual sales $90,500$ units

Materials costs $(508,000$ ounces$)$ $ $?$

Materials price variance $63,200$ U

Materials efficiency variance $71,120$ U

Direct labor price variance $18,850$ F

Direct labor $(37,700$ hours$)923,650$

Overapplied overhead $($total$)25,300$

There are no materials inventories.

Required:

a$.$ Prepare a variance analysis for direct materials and direct labor.

b$.$ Assume that all production overhead is fixed and that the $$25,300$ overapplied is the only overhead variance that can be computed. What are the actual and applied overhead amounts?

c$.$ Complete the standard cost sheet for a device given below.
