D. the quantity demanded is not responsive to price changes. E. a change in the quantity demanded brings a small change in the price of the good. © 2013 Pearson CHECKPOINT 5.1 Question 2 The price of a bag of pretzels rises from $2 to $3, and the quantity demanded decreases from 100 bags to 60 bags.

E. decreases if demand for its product is unit elastic increases if demand for its product is unit elastic decreases if demand for its product is inelastic increases if demand for its product is elastic decreases if demand for its product is elastic © 2013 Pearson CHECKPOINT 5.2 Question 4 If, when the price of a good rises by 10 percent, the quantity supplied of the good increases by 5 percent, then the elasticity of supply ________. A. B. C. D. E. exceeds 1, and the supply of the good is elastic is negative, and the supply of the good is inelastic is less than 1, and the supply of the good is elastic is less than 1, and the supply of the good is inelastic exceeds 1 and the supply of the good is inelastic © 2013 Pearson CHECKPOINT 5.2 Question 5 The greater the amount of time that passes after the price of a good changed, the ___________ of that good becomes. A. B. C. D. E. less elastic the supply more elastic the supply more negative the supply steeper the supply curve more inelastic the supply © 2013 Pearson CHECKPOINT 5.2 Question 6 The supply of beachfront property on St. Simon’s Island is ________.
