Assume that for a given consumer, the marginal utility of Dryer's Ice Cream is 120, and the price of Dryer's Ice Cream is $4 per gallon. Also, assume that the marginal utility of Blue Bell Ice Cream is 160, and the price of Blue Bell is $5 per gallon. Given this information and what you've learned about demand and decision making, which is true about this consumer?
consumer should buy more Blue Bell, it's provides more utility at a marginally higher price.
The schedule that shows how many units of a good the consumer will purchase at different income levels that helps us classify normal and inferior goods is known as what?
engel curve
If there were no budget constraint, consumers would move to consume all goods and services at a point at which marginal utility of each good is ten.
false
In the case of a normal or luxury good, a rise in income will lead to a downward shift in the consumer's demand curve.
false
The Law of Demand can be simplified to say that consumers demand more at a higher price.
false
These types of goods will have decreased consumption when a consumer's income increases and increased consumption when a consumer's income decreases.
inferior goods
These types of goods will have increased consumption when a consumer's income increases and will have decrease consumption when a consumer's income decreases.

Consumption bundle
particular combinations of goods being considered

Isoutility curve
represents the combination of consumption bundles that provide a consumer a given level of satisfaction
Utility is another word for?

Law of diminishing return
suggests that as consumption per unit of time increases, marginal utility decreases.
The slope of an isoutility curve represents what?
the Marginal Rate of Return
Marginal utility
the change in utility or satisfaction due to the change in consumption of that good.
