Last year, for every 100 million vehicles that traveled on a certain highway, 96 vehicles were involved in accidents. If 3 billion vehicles traveled on the highway last year, how many of those vehicles were involved in accidents? (1 billion=1,000,000,000)

96 accidents per 100 million = 960 accidents per billion.
Multiply 960 by 3 to get 2880 per 3 billion. (you don't even have to do the multiplication, as you know it will be just short of 3000 and answer C is the only answer just short of 3000.)
