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.

Answer:
u^2 + 9
Step-by-step explanation:
you would have to put the exponent on the u and 3
so it would by u^2 + 3^2
but simplified it would be
u^2 + 9
we cannot simplify further since we don't know what u equals

Answer:
£6655
Step-by-step explanation:
Given data
Principal= £5000
Rate= 10%
Time = 3 years
FInal Amount A=???
The expression for the compound interest is given as
A=P(1+r)^t
substitute
A=5000(1+0.1)^3
A=5000(1.1)^3
A=5000*1.331
A= £6655
Hence the final Amount is £6655
