The formula S=3x^2-18x+84 models spending by international travelers to a certain country, in billions of dollars, x years after 2000. Use the formula to determine in which years international travelers spent $60 billion.

S=3x^2-18x+84
60=3x^2-18x+84
3x^2-18x+24=0
x^2-6x+8=0
(x-4)(x-2)=0
x=4 and x=2
ans:
Years international travelers spent $60 billion=2004 and 2002
