Complete Question
A waiting line problem has an average of 250 arrivals per eight hour day. Suppose there are several servers, and each has an average service time of 8 minutes. (Assume Poisson arrivals and exponential service times.)
What is the average service rate of a server per hour?
Answer:
7½ arrivals per hour
Explanation:
Given
Arrivals = 250 arrivals per 8 hour day
Service Time of Servers = 8 minutes
The service time of Servers is given as 8 minutes.
This means that; on average, a server will attend to 1 arrival in every 8 minutes.
Calculating this per hour;
Average service rate of a server per hour = Service Rate * 1 hour per hour
Average service rate of a server per hour = 1 arrival per 8 minutes * 1 hour per hour
(1 hour = 60 minutes);
So, we have.
Average service rate of a server per hour = 1/8minutes * 60minutes/hour
= ⅛ * 60 arrivals/hour
= 60/8 arrivals/hour
= 7½ arrivals per hour

Answer:
The correct answer is: reduce; price; supply; poor.
Explanation:
A tariff is a tax imposed on the import of goods and services from another country. A quota is a quantitative restriction on the imports.
Both tariff and quotas decreases the supply of imported products. This causes their price to increase. This increase in price reduces the consumer surplus for the domestic consumers.
In some cases where tariff is imposed on cheap goods that are consumed mostly by the poor consumers hurt them the most. Tariff in such situations become an example of regressive tax.
