Merg makes fireworks to be sold around the world. The standard costs for the most popular product, the X Rocket that initially looks like a green tree, with leaves that turn red and gold and then drop to the ground, is as follows:

DM (5.6 pounds of gunpowder @ $5 per pound) $28

DL (30 minutes @ $20/hour) 10

VOH (2 MH @ 4.5/hour) 9

FOH (2 MH @ 15.50/hour) 31

TOTAL COST $78

The DM price standard was computed based on the desired quality of gunpowder and includes an expected quantity discount. Shipping and import fees are paid for by the supplier. The use of hazardous materials fee is assessed by the government. The DM quantity standard is based on the amount required to fill the chamber with the exact right combination of colours. Any carelessness in production can cause explosions. Also, if the colours are not precisely correct, the rockets fail the quality control inspection.

The DL rate standard is based on the average hourly wage adjusted for benefit, which is very liberal in this firm. The DL quantity standard is based on the amount of time required to fill and seal the chamber. There is an adjustment for product failures, as well as explosion before sealing and quality control failures.
