Explanation / Answer

S(x) = -1.749x^2 + 39.292x + 378.009

b) sales of 550 billion dollar

plug y = 550

550 = -1.749x^2 + 39.292x + 378.009

solving for x

subtracting 550 from both sides and applying quadratic formula

x = 5.957 , x = 16.509

therefore, in the year 2007 the sale is 550 billion dollars
