2.Price will increase and quantity increase.
3.Price will decrease and quantity increase.
4.Price will decrease and quantity decrease.
5.No change in equilibrium and quantity will occur.

9.Two separate groups of people use New York City subways. One group uses them only during rush hour to travel to and from work. The other group uses them only in midday for leisure activity. If New York City wants to increase transit fares with the smallest possible reduction in revenue, for which group should it increase the fare?
1.The rush-hour group because its demand for subway service is more elastic than that of the midday group.
2.The rush-hour group because its demand for subway service is less elastic than that of the midday group.
3.The midday group because its demand for subway service is more elastic than that of the rush-hour group.
4.The midday group because its demand for subway service is less elastic than that of the rush-hour group.
5.It doesn't matter because both groups have the same elasticity of demand.

10.As price falls along a given demand curve for pretzels,
1.quantity demanded, total utility, marginal utility, and consumer surplus increase; consumer expenditure decreases.
2.quantity demanded, total utility, and consumer surplus increase; marginal utility and consumer surplus decrease

4.quantity demanded, total utility, and consumer surplus increase; marginal utility decreases; consumer expenditure might increase, decrease, or remain constant
5.quantity demanded, total utility, marginal utility, consumer surplus, and consumer expenditure all increase
