Answer: <em>the answer would be</em> <em>C</em>, 12.
People in the U.S spend 18.8 billion dollars in 2009.
<h3>What is substituting ?</h3>
Substituting in mathematics is putting a specific value in an independent variable to observe a system.
According to the given data
Statins is the top selling drug in US to keep cholesterol in check.
The equation of the sales (S) of statin in billons of dollars x years after is
S - 1.3x = 4.5
The year difference is (2009 - 1998) = 11 years or x = 11
Putting the value of x in the given equation
S - 1.3(11) = 4.5
S = 4.5 + 14.3
S= 18.8
∴ The number of sales of statin is $18.8 billions.

Step-by-step explanation:
Answer:
Megan will have to pay $2, 260 for surgery.
Step-by-step explanation:
1. Translate percent into decimal:
90% -> 0.9
2. Multiply (to find out how much the insurance company pays):
(0.9)(14, 600) = 13, 140
3. Subtract:
14, 600 - 13, 140 = 1, 460
4. Add (to find out how much Megan pays):
1, 460 + 800 = 2, 260
The student should compute 6*180 = 1080 because of the formula
S = 180(n-2)
We have n = 8 sides which leads the n-2 part to become n-2 = 8-2 = 6
