Answer:
Total standard cost = $103.7
Explanation:
Standard cost is the sum of the standard material cost , standard labour cost and standard overhead
Overhead  = OAR × direct labour hour
        = $16 × (0.30×$19.00)= 91.2
Standard cost = (34.0Ă—$0.20) + (0.30Ă—$19.00) + Â 91.2 = $103.7
Standard cost = $103.7
