Misty spends her entire weekly allowance of 15 on two goods: T-shirts (which cost 10 each) and lipstick (which costs 5).
 
  What is the opportunity cost of a T-shirt? If her parents raise her allowance to 20 per week, what happens to the opportunity cost of a T-shirt?

Question 2

Briefly describe changes in life expectancy, average height, and infant mortality in the United States since 1850.
 
  What will be an ideal response?

Answer to Question 1

The opportunity cost of a T-shirt is 2 lipsticks. If her parents change her allowance, the opportunity cost of a T-shirt is unaffected.

Answer to Question 2

Life expectancy has increased from 38.3 years in 1850 to 79.6 years in 2015. The average height of adult males has increased from 5'7 in 1850 to 5'9.5 in 2015. Infant mortality has dropped from 228.9 per 1,000 live births in 1850 to 6.2 per 1,000 live births in 2015.
