Chemistry 11
The thin outer layer of Earth, called the crust, contains only 0.50 percent of Earth's total mass and yet is the source of almost all the elements (the atmosphere provides elements such as oxygen, nitrogen, and a few other gases). Silicon (Si) is the second most abundant element in Earth's crust (27.

Principles of Economics 6
The residents of Vegopia spend all of their income on cauliflower, broccoli, and carrots. In 2010, they buy 100 heads of cauliflower for $200, 50 bunches of broccoli for $75, and 500 carrots for $50. In 2011, they buy 75 heads of cauliflower for $225,80 bunches of broccoli for $120, and 500 carrots f

Urban Economics 8
The city of Medianville has 100 citizens with income ranging from $20,000 to $70,000. The average income is $50,000 and the median income is $60,000. An individuals demand for open space depends only on income, and the indi- vidual demand curve (marginal benefit curve) has a vertical intercept equal
