If the revenue of a business during the year is $88 million, its cost of goods sold is $40 million, its operating expenses (including depreciation) are $10 million, interest payments and other financial expenses are $4 million, and taxes are $6 million. What is the annual net income (or annual net profits) of this business? (Type in your numerical answer in million $ units. Do not type the $ sign or the word million, just the number in decimal notation. If the annual net income is negative, indicate so with the minus sign before the number.)
