Last year, for every 100 million vehicles that traveled on a certain highway, 75 vehicles were involved in accidents. If 6 billion vehicles traveled on the highway last year, how many of those vehicles were involved in accidents? (1 billion = 1,000,000,000) Select the correct option.
A) 2500	B) 4500	C) 3500	D) 4000	E) 1300
To solve we will set up a proportion. We know that “100 million vehicles is to 75 accidents as 6 billion vehicles is to x accidents”. To express everything in terms of “millions”, we can use 6,000 million rather than 6 billion. Creating a proportion we have:   100/75 = 6,000/x   Cross multiplying gives us:   100x = 6,000 * 75   x = 60 * 75=
