I want to know the answer to the following question:
Madonna generated how much in sales in the first 10 years of her career?
All the background I'm provided with is that "Madonna has received acclaim as a role model for businesswomen in her industry, "achieving the kind of financial control that women had long fought for within the industry", and generating over $1.2 billion in sales within the first decade of her career.". Is that enough to answer the question?
