b. grant british investors fifty percent of the ownership of any colonial commercial or manufacturing enterprise.

C. Furnish raw materials to the mother country and buy British manufactured goods.

Mercantilism was the trade theory followed by the European powers from 1500 to 1800. This theory advocated that the nation should export more and import less to accumulate bullion. The export of finished goods was supported by the primary industries. It was the reaction to the economic problems caused when the states were too weak to control their economies and  for the development of their, the countries started to occupy colonies. The colonies were a major sources of raw materials for mercantile powers and also served as a market. England put the theory of mercantilism into English colonies by Navigation Acts.
