A company earned $2,880 in net income for October. Its net sales for October were $12,000. Its profit margin is:

profit margin = 23.33%

Explanation:

profit margin = net profit /  net sales

profit margin = $2,800 / $12,000 = 0.233333 = 23.33%

The profit margin is a profitability ratio used to compare how many cents different companies are able to make from selling $1. Different companies have different sales levels, but we can group companies by industries and then compare them in order to determine which ones are more efficient at generating income. E.g. Company A sells $100 million but only makes $2 million in profits per year (PM = 2%), and it is much less efficient than Company B that sells $10 million and makes $1 in profits (PM  = 10%). Company A's costs are too high compared to Company B's costs.  

the answer is "b.the increased supply will create a surplus. "

the essential thought behind price controls is straightforward - utilize the power of law to modify the equilibrium of a market. for instance, the legislature may choose that the steel business needs to survive, and in this way pass a law to set a value floor on steel. this implies all steel sold must offer at or over the floor value, which must be set over the equilibrium cost for it to have any impact. the switch could likewise happen - the administration can choose that steel is excessively costly and set a value roof underneath its equilibrium value, with the goal that all steel must be sold at or beneath that ceiling.
