Answer:
<u><em>Part 1. </em></u>
- <em>Average cost per day of a three-day pass</em> = $53.33/day per person
- <em>Marginal cost of adding the third day </em>= $190 - $160 = $30 per person
<em />
<em><u>Part 2.</u></em>
- <em>Group's marginal cost of switching from the two-day pass to the three-day pass</em> = $180
Explanation:
The total <em>cost</em> is the <em>admission charge</em> ($60) plust the cost of the pass ($100 or $130).
For a <em>two-day pass</em> that is: $60 + $100 = $160, per person
For a <em>three-day pass</em> that is: $60 + $130 = $190, per person
<u><em>Part 1. The average cost per day of a three-day pass per person. </em></u>
The <em>average cost</em> is the total cost divided by the number of days.
- <em>Average cost</em> = $160/3days = $53.33/day per person
The <em>marginal cost of adding the third day</em> per person is found by subtracting the total cost for two days from the total cost for three days:
- <em>Marginal cost of adding the third day</em> = $190 - $160 = $30 per person
This says that althoud the average cost for the three days is $53.33 the cost of adding the third day is $30, which is much lower; thus, it is a good deal to buy a three-days pass, as they are interested in spending a lot of time there.
<u><em>Part 2. The group's marginal cost of switching from the two-day pass to the three-day pass</em></u>
<em></em>
Since the <em>marginal cost of switching from the two-day pass to the three-day pass</em> is $30 per person, the marginal cost for the 6-person group is 6 times $30:
- 6 persons × $30/person = $180.
Answer:
If an economist argues that everyone gains from trade, the following reasoning is most likely underlying her argument:
- Production according to the principle of comparative advantage lowers overall costs and therefore allows both countries to have a higher standard of living.
Explanation:
- The comparative advantage refer to the situation in which an individual, company or a country offers its services and products at a lower rate as compared to its competitor. This leads to trade-off as you have to comprise for the gain of something.
- This comparative advantage also increase the dependencies of nations or companies on each other.
- For example, England and Portugal has benefited from this comparative advantage concept as England get the wine at lower cost from Portugal and Portugal also get earning by selling this wine to England.
