Extrapolating - so, a CD store which was around 35 years ago = (one million years) and an LP store about 50 years ago, (asking my husband how to extrapolate, he knows the formula, but he doesn't know if it's called "extrapolating" - he's a foreigner). LP stores (Tower Records in San Diego) would be l,430,000 dollars. Did I do it right?

If I sell Double Fantasy for 2.5 millions dollars, I will be rich. Thanks for the tip, Sarah.
