Answer:
19 billion dollars
Step-by-step explanation:
Given the equation :
S - 1.3x = 6
Where, S = amount of sale of statin in billions of dollars ; x = number of years after 1998
Amount spend in 2008
x = 2008 - 1998 = 10
Put x = 10 in the equation ;
S - 1.3x = 6
S - 1.3(10) = 6
S - 13 = 6
S = 6 + 13
S = 19
People will spend about 19 billion dollars on statin in 2008
