This question contains multiple parts; be sure to answer each.

First, what is motivation, and why is it important for managers to understand how motivation works?

Second, suppose that you are the manager of a Salvation Army store. People make donations to the store as charitable contributions, and then the store sells the items to raise money for its charitable projects (mostly designing programs to offer immediate relief, short-term care and long-term growth in the areas that will best benefit the community). Name at least one extrinsic and one intrinsic reward you might use to motivate employees at the store.
