send a memo to current coworkers

Steve should create a type of business report called a business plan. The correct option among the options that are already given in the question is the last or the fourth option. This business report created by Steve will actually influence the investors about investing their money in Steve's business. this business report will have all the details about the business, the amount of investment required and the amount of expected profit.

In order to help the student expand his/her knowledge I will help answer the question. This in hope that the student will get a piece of knowledge that will help him/her through his/her homework or future tests.

If Steve wants to start his own used bookstore and is looking for investors. He should make a business plan where he will describe what the purpose of this business will be and what goals does he intend to accomplish and how will he achieve this goals. This way investor can make an educated decision to whether or not invest.

Steve should create a type of business report called a business plan.
