Answer :

ANSWER

[tex]S\text{ = \$15.2 billions}[/tex]

EXPLANATION

Given information

[tex]S\text{ - 1.3x = 6.1}[/tex]

Where

S is the amount of sales of statin in billions of dollars

x is the number of years

Step 1: Calculate the number of years

[tex]\begin{gathered} Recall,\text{ that the sales was from 1998 to 2005} \\ x\text{ = 2005 - 1998} \\ x\text{ = 7 years} \end{gathered}[/tex]

Step 2: Find the amount of sales in billions of dollars using the given modeled equation

[tex]\begin{gathered} S\text{ - 1.3x = 6.1} \\ S\text{ - 1.3\lparen7\rparen = 6.1} \\ S\text{ -9.1 = 6.1} \\ Add\text{ 9.1 to both sides of the equation} \\ S\text{ - 9.1 + 9.1 = 6.1 + 9.1} \\ S\text{ = \$15.2 billions} \end{gathered}[/tex]
