Answer:
They bought raw materials from the colonies and sold them finished products.
Step-by-step explanation:
As you may already know, the American territory is richer biologically than Europe. In this case, European nations with American colonies achieved a lot of profits from mercantilism, because they had strong access to the natural resources of their colonies, which served as raw material for the production of finished products. In the case of British mercantilism, the British took raw materials from America and produced finished products that they sold to other colonies, including the American ones. An example of this is cotton, which was extensively explored in the south of the country and sent to England to produce fabrics.
