Last year, for every 100 million vehicles that traveled on a certain highway, 40 vehicles were involved in accidents. If 2 billion vehicles traveled on the highway last year, how many of those vehicles were involved in accidents? (1 billion = 1,000,000,000) Choose the most appropriate option
A) 800	B) 900	C) 100	D) 1000	E) 950
To solve we will set up a proportion. We know that “100 million vehicles is to 40 accidents as 2 billion vehicles is to x accidents”. To express everything in terms of “millions”, we can use 2,000 million rather than 2 billion. Creating a proportion we have:   100/40 = 2,000/x   Cross multiplying gives us:   100x = 2,000 * 40   x = 20 * 40=
