Which term describes assets earned from operations that's have been reinvested into business

An asset earned from operations is known as revenue, or more precisely as net income (the net value of assets earned (revenue) minus assets sacrificed (expenses)). A percentage of this net income is given back to shareholders as dividends. The portion that stays in the company, presumably to be reinvested into the business, is called Retained Earnings. 

65+15-15=65 can be the answer!!
