Answer:
An investment center
Step-by-step explanation:
A division, firm, work team or department that directly contributes to the company's profit gain is referred to as an investment center. On the contrary, a cost center is a department that does not directly contribute to profit, but represents mainly a cost for the company, although it benefits the business.
