Answer: $1,794.40 Unfavorable
Step-by-step explanation:
Total labor variance = Actual cost of labor - Standard cost of labor
Actual cost of labor = $40,400
Standard cost of labor = Hours per unit * Cost per hour * Number of units
= 2.2 * 10.70 * 1,640
= $38,605.60
Total labor variance = 40,400 - 38,605.60
= $1,794.40 Unfavorable
Unfavorable because actual cost of labor was greater than the standard cost.
