At the beginning of the year, Lopez Company had the following standard cost sheet for one of it's chemical products:

Direct Materials (4 lbs @ $2.80) - $11.20

Direct Labor (2 hrs @ $18.00) - 36.00

FOH (2 hrs @ $5.20) - 10.40

VOH (2 hrs @ $0.70) - 1.40

Standard Cost Per Unit - $59.00

Lopez computes its overhead rates using practical volume, which is 90,000 units.

The actual results for the year are as follows:

(a) units produced: 88,000

(b) direct labor: 170,000 hours

(c) FOH: $930,000 and

(d) VOH: $125,000
