Q Question 1 1 / 1 pts For consumers who don't want to be locked into a long-term cell phone contract, a number of cell phone companies offer "Pay As You Go" (PAYG) plans. Consider a PAYG plan featuring a basic calling rate of 20 cents per minute (with no activation, cancellation or other fees). PAYG-type plans are most appealing to people who are not heavy users of cell phones or who have only a temporary need for a phone (like travelers). Consider Linda Cooper, who will be visiting the U.S. for one month. She estimates her monthly demand for phone calls while in the U.S. to be q = 232 - 4P (where q is minutes of phone calls and P is measured in cents). How many minutes of calls per months will Linda make? Question 2 1 / 1 pts An increase in consumer incomes will lead to Question 3 1 / 1 pts An individual consumer has chosen to buy Q0 units of a good this year, at a price of P0 per unit. Total willingness to pay for these Q0 units by this consumer can be represented by their demand curve as: Question 4 1 / 1 pts An individual who is only willing to pay a relatively low amount for a particular good

1.Linda will make 152 minutes of calls per month. 2.a rightward shift of the demand curve for LCD TVs. The demand curve captures the quantity consumed at every possible price, everything else being equal. If consumer incomes increase, then for any given price, more consumers have available income to purchase LCD TVs (or the same consumers have available funds for more LCD TVs). As a result, the quantity demanded for any given price increases, captured by a rightward shift of the demand curve. 3.The area under the demand curve, up to the quantity Q0 The total willingness to pay is the area under the demand curve up to the quantity consumed, which in this case is Q0. This comes from summing the willingness to pay for consuming each unit, which is measured by the height of the demand curve for each unit, up to Q0.
