Answer: 
-$3,547 unfavorable 
Explanation: 
For the computation of labor rate variance for January first we need to find out the standard direct labor cost which is shown below:- 
Standard Direct labor cost = Produced units × Standard quantity of direct labor × Standard price of direct labor 
= 3,440 × 0.8 × $33 
= $90,816 
Labor rate Variance = Standard direct labor cost - Actual labor cost 
= $90,816 - $94,363 
= -$3,547 unfavorable 
Therefore for computing the labor rate variance we simply applied the above formula.
