Question

Statins are used to keep cholesterol in check and are a top-selling drug in the U.S. The equation: S − 1.9 x = 5.7 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 2011?

Answer 1

Answer:

30.4 billion dollars

Step-by-step explanation:

We have been given an equation $S-1.9x=5.7$, which gives the amount of sales ( S ) of statin in billions of dollars x years after 1998.

To find the amount spent on statins in 2011, we will substitute $x=13$, in the given equation as $2011-1998=13$.

$S-1.9x=5.7$

$S-1.9(13)=5.7$

$S-24.7=5.7$

$S-24.7+24.7=5.7+24.7$

$S=30.4$

Therefore, people in the U.S. spend 30.4 billion dollars on statins in the year 2011.
