In this report, there are three variables being
mentioned. These are:
1st variable = 19 minutes
2nd variable = 7 jumps
3rd variable = 79%
In this problem, I believe what we are asked to do is to
identify the type of variable the 2nd variable is. We are given that
the 2nd variable is “7 jumps”.
This means that the 2nd variable is quantitative because it
refers to or relating to a measurement of something rather than the quality. We
also know that jumps can only take whole numbers, not decimal. Therefore it is
also discrete. Hence, the 2nd variable is:
quantitative and discrete
Answer:
Explanation:
Please have a look at the attached photos, for this type of question, we need to draw!
a. From this information, derive Bert’s demand schedule. Graph his demand curve for bottled water.
Price Quantity Demanded
More than $7 0
$5 to $7 1
$3 to $5 2
$1 to $3 3
$1 or less 4
b. When the price of a bottle of water was $ 4, Bert bought 2 bottles of water. Consumer surplus of him is shown as area A in Fig. He valued his first bottle of water at 7 dollars, but only pay 4 dollars for it, so the consumer surplus is $ 3. He valued his second bottle of water at 5 dollars, but only pay 4 dollars for it, so the consumer surplus of $ 1. Therefore, the total consumer surplus of $ 3 + $ 1 = $ 4, is in the area of A
c. When the price of a water bottle dropped from $ 4 to $ 2, Bert bought three bottles of water, increasing it. His consumer surplus includes both areas A and B in the figure, an increase in the number of areas B. He gets a $ 5 consumer surplus from the first bottle ($ 7 minus $ 2 ), $ 3 from the second bottle (minus $ 5 The $ 2 price) and $ 1 from the third bottle ($ 3 minus $ 2), with a total consumer surplus of $ 9. Therefore, consumer surplus increased $ 5 (which is the size of area B) when the price of a bottle of water dropped from $ 4 to $ 2.
Money encourages specialization by decreasing the exchange cost.
The correct option is B.
<h3>What is the exchange cost?</h3>
Exchange cost is the price by which the product is exchanged between the customer and seller.
Money eliminates the double coincidence of desires, allowing for greater specialization and productivity.
As a result, money enables us to make better use of our limited resources by allowing us to generate more in the same number of resources.
This aids in the reduction of scarcity.
Thus, B is the correct option.
