1) The 2010 prison population in the united states was approximately 1.6 million. How many arenas with a capacity of 50,000 would this population fill?
2) In 2011, sales of Bud Light (beer) totaled $1.45 billion. Express this quantity in terms of the heigh in kilometers of a stack of $1 bills. Assume 10 bills per millimeter.
+37093 1.6 million people / 50000 people/arena = 32 arenas
$1450000000/ $10/mm = 145000000 mm = 145000 m = 145 km
