Answer: (a ) 4 per hour (b ) 4.5 minutes (c ) 3 minutes

Explanation:

Average time between customer arrival = 15 minutes

Average service time = 10 minutes

(a) To calculate the customer arrival rate

Arrival rate = 1 / time between Arrival

= 1 / 15

= 0.066 × 60

= 4 per hour

(b) To calculate the average number of customers in queue

( Arrival time )^2 / service time ( service time - Arrival time)

= (15)^2 / 10 ( 10 - 15)

= 225 / 10 (-5)

= 225 / 50

= 4.5 minutes

(c) To calculate the average time customers spend in the system

Arrival time / service time - Arrival time

= 15 / 10 - 15

= 15/ -5

= 3 minutes

Natalija [7]

Answer: e. To drive up market share

Explanation:

Differentiation strategies involve adding features to a good to make it stand out from the Competition. Since these features are usually beneficial, the value of the good goes up and the company selling them can charge more. This is the main way things are done in Monopolistic markets.

However, sometimes it is best to charge the same price the Competition is charging even though you have a better product. This way the company is able to capture Market Share because the consumers will believe they are getting a better value for their money. For instance, if a company was selling Toyotas at $2,000 and it's competitor was selling the same Toyota but with 2 extra tires for the same $2,000 who would you use? The Competitor most likely.

This is why a firm might want to keep prices in line with competitors.
