#### Problem: If Tom has three times as many apples as Susan and Susan has one-fourth as many as Joe, who has 4, how many does Mary have if Mary has two more than Tom?

(Use Mary's, Tom's Susan's and Joe's for the variables.)

 The problem asks for the number of apples Mary has. The problem states that Mary has two more than Tom . This equation requests information about the number of apples Tom has. The response to this request is in the beginning of the problem statement. The equation just written requests information about Susan's. The problem tells us that she has one-fourth as many as Joe. This equation requests Joe's. The problem provides the response to this request. The result of substitution is The result of doing the arithmetic is Respond to what is asked for at each step. ``` ``` Learn the ideas used in solving this problem well.
