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 = 4.9 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 2005? Answer: People in the U.S. Will spend billion dollars on statins in 2005.

Answer 1

People in the U.S. Will spend 18.2 billion dollars on statins in 2005.

Explanation:

Given:

S − 1.9x = 4.9

Where,

S = sales of statin in billions of dollars

x = years after 1998

how much will/did people in the U.S. Spend on statins in the year 2005?

2005 is a year after 1998

Number of years = 2005 - 1998

= 7

x = 7 years

S − 1.9x = 4.9

S - 1.9(7) = 4.9

S - 13.3 = 4.9

Add 13.3 to both sides

S = 4.9 + 13.3

= 18.2

People in the U.S. Will spend 18.2 billion dollars on statins in 2005.
