S-1.5x=5.8 gives the amount of sales (S) of statin in billions of dollars x years..

Question

Statins are used to keep cholesterol in check and are a top-selling drug in the U.S. The equation: S-1.5x=5.8 gives the amount of sales (S) of statin in billions of dollars x years after 1998. According to this equation, how much will/did people in the U.S. spend on statins in the year 2017? Could anyone help me with this one by chance?

Answer 1

s=1.5x+5.8..... x=num yeers aft 1998... want s for yeer=2017, so 2017-1998 giv x=19... s=1.5*19+5.8... s=28.5+5.8... s=34.3
