In Vietnam, the Americans actually fought â therefore in the Cold War âgameâ, the USSR could not. However, to support the Communist cause, the Soviet Union armed its fellow Communist state, China, who would, in turn, arm and equip the North Vietnamese who fought the Americans. Before World War Two, Vietnam had been part of the French Empire. During the war, the country had been overrun by the Japanese. When the Japanese retreated, the people of Vietnam took the opportunity to establish their own government lead by Ho Chi Minh.
Gross (unit) A gross refers to a group of 144 items (a dozen dozen or a square dozen). A great gross refers to a group of 1728 items (a dozen gross or a cubic dozen). A small gross or a great hundred refers to a group of 120 items (ten dozen).
Gross Margin. Gross margin represents the percentage of net sales that the firm takes in as gross profit. It equals gross profit divided by net sales. If you have sold $500,000 worth of product, and the cost of goods sold is $300,000, the gross profit is $200,000. The gross margin is $200,000 divided by $500,000 which equals 40 percent. A business should not focus on gross margin exclusively, since you can increase gross margin but end up with less in gross profits. If your gross profits drop to $170,000 and sales decline to $400,000, gross margin would be higher, at 42.5 percent, yet gross profits would be $30,000 lower. Contribution Margin Contribution margin is a more relevant measure to assess the profitability of additional products sold, and only takes into account variable costs.
