A central issue of the nineteenth century is the global domination of Western culture.  Explain how the ideas of the Romantic Hero, slavery and abolitionism, and nationalism, all contribute to that domination. Analyze specific examples.

The price of a product increases from $8 to $12, while quantity demanded decreases from 60 units to 40 units. Using the midpoint method, what is the price elasticity of demand?  

Marginal utility is:  

Suppose consuming three slices of pizza gives Maria 45 units of total utility, while consuming four slices gives her 55 units of total utility. What is the marginal utility of the fourth slice?

If the consumer has a budget of $45, which combination will maximize total utility?

A perfectly inelastic demand curve has an elasticity equal to:  

A 10% increase in the price of a product causes quantity demanded to decrease by 20%. What is the price elasticity of demand?
