Dehli Inkstone specializes in inkstone creation. Each finished inkstone needs 1 pounds of special materials which cost $20 a pound. (One pound contains 16 ounces.) Drilling requires 1 direct labor hours, for which workers are paid $10 per hour, and 40 minutes of machine time. The preliminary product (a 'basic') is inspected to ensure that it is sound. Fifteen percent of the basics are rejected. It is not possible to rework these, and they have no salvage value. Each approved stone is handed to a master craftsperson who spends two hours making a 'Standard' product or three hours creating a 'Masterpiece'. Standards use half an hour of machine time and Masterpieces one hour. Finished inkstones are inspected again before packing. Four percent of finished products fail the final quality control assessment and are destroyed. Crafts persons are paid $18 per hour. It takes a 'basic' worker six minutes to package each inkstone in bubble wrap and a shipping carton, which cost 50 cents in materials and weigh 6 ounces in total.

Total overheads are estimated to be $587,400 per year and 97,900 direct labor hours are budgeted. Production plans for the year call for 60% of output to be Standard inkstones and the balance Masterpieces.

Dehli Inkstone recently employed a cost analyst, who recommended the adoption of an ABC system to obtain a more accurate understanding of the costs of the Standard and Masterpiece products. She has classified the overheads into the following four cost pools and identified the appropriate cost drivers:

Cost Pool Dollars Cost Driver

Materials handling $ 121,000 Pounds of raw materials

Inspection $ 48,400 Inspections

Machine operation & maint. $ 163,350 Machine hours

Labor-related costs $ 254,650 Direct Labor dollars

Total $ 587,400

Independent of your answers above, assume total planned output is 25,595 units.What is the correct materials handling cost rate?

$2.209 per lb.

$2.521 per lb.

$2.136 per lb.

$2.572 per lb.

None of the above
