The following computations of March labor variances for Sam's Supply Company are incomplete. The missing items are labeled (a) through (d).
Labor rate variance = 4,800 hours ´ [(a) - $8.50] = $350 favorable
Labor efficiency variance = (b) ´ [(c) - 5,000 hours] = $(d)
On the appropriately labeled line, identify each missing item by name (a through c) and show the missing value (a through d). Show supporting computations in the space provided.
