At a price of $0.50, the amount of cups of lemonade that Caroline and Emily sell when the temperature is 60 degrees than when the temperature is 80 degrees is <u>-</u><u>1</u><u>5</u>.
50 - 80 = -30
= -30 * 0.5
= - 15
<h3>How does one arrive at the answer?</h3>
This is an instance of demand curve shift which refers to key changes in the balance of supply and demand that alter the quantity demanded at the same price. Hence, the shift in the quantity demanded will affect the amount of cups of lemonade that is sold.
Sometimes questions that involve graphs will ask you to consider the effect of a changing factor or factors. Problem statement: the line labeled D1 in the graph to the right shows the number of cups of lemonade that Caroline and Emily can sell at their lemonade stand at various prices.
Caroline and Emily have noticed that they sell more lemonade when it's hotter. Click anywhere on the graph to open a window with a control labeled Temperature. If you use the slider to change the temperature, the line will shift. Change the temperature from 80 degrees to 50 degrees.
At a price of $0.50, the amount of cups of lemonade that Caroline and Emily sell when the temperature is 60 degrees than when the temperature is 80 degrees is<u> -15</u>.
Therefore, the correct answer is as given above

The question is incomplete. Here is the complete question
Suppose the demand for Digital Video Recorders (DVRs) is given by Q = 250 - .25p + 4pc, where Q is the quantity of DVRs demanded (in 1000s), p is the price of a DVR, and pc is the price of cable television. How much does the quantity demanded for DVRs change if the p rises by $40? A) drops by 10,000 DVRs B) increases by 16,000 DVRs C) drops by 2,500 DVRs D) increases by 4,000
Answer:
Drops by 10,000 DVRs
Explanation:
The demand for digital video recorders is expressed by
Q= 250- .25p+4pc
Where
Q represents the quantity demanded by the customers
P represents the price of DVR
pc represents the price of cable television
Since the factor of p in the expression above is negative, this implies that the quantity of DVR demanded in the market will reduce
If the price of DVR increase by $40, then the quantity demanded will reduce by
= 0.25×40×1000
= 10×1000
= 10,000 units
Hence the quantity of DVRs drops by 10,000 DVRs if the price is increased to $40
Answer: Trade between the two countries is beneficial when United States trade food to Canada and Canada would trade televisions to the United States.
Explanation: In international trade, each country will produce a good in which it has a comparative advantage (lower opportunity cost).
Opportunity cost of food is,
Unites states = 
Canada = 
Opportunity cost of television is,
Unites states = 
Canada = 
Since, opportunity cost of food is lower in the United states, United states will export food.
Opportunity cost of television is lower in Canada, Canada will export television to the United States.
