To determine the cost of manufacturing one picture frame, add all the known cost by the number of frames produced. With the basis of one hour of operation,
Cost of wood per frame = $18.75 / 15 = $1.25
Cost of direct labor per frame = $ 13.50 / 65 = $ 0.21
Adding all up the costs,
total cost = $1.25 + $0.21 = $1.46
Therefore, manufacturing one picture frame costs approximately $1.46.
