Answer:

The average time spent waiting in line for each student is 2.25 students.

Explanation:

Use Lq with a single server formula.

λ = Avg arrival rate  = 15 std/hr

μ= Avg server rate (individual server capacity) = 20 std/hr

Μ = # of servers/line (identical capacities)

= λ^{2}/μ(μ- λ)

=15^{2} / 20(20-15)

= 225/100

=2.25 students.

A= (1000000*0.08)/(1.08^36-1)

A= 80000/14.96817184

A= 5344.67

ratelena [41]

Answer:

10.52%

Explanation:

The computation of the annual financing cost is shown below:

First we have to calculate the interest cost that is shown below:

= $997.26

Now the used funds is

= $20,000 - $997.26

= $19,003

Now the annual financing cost is

= ($997 ÷ $19,003) × (365 days ÷ 182 days)

= 10.52%

We assume there are 365 days in a year

The language of price controls
mel-nik [20]

Answer:

1) The government prohibits gas stations from selling gasoline for more than $3.40 per gallon.  

This statement is an example of price ceiling as the gas stations cannot raise their price above $3.40 but can sell it at any price lower than the ceiling price of $3.40. This is binding

2) Due to new regulations, gas stations that would like to pay better wages in order to hire more workers are prohibited from doing so. This is neither a price ceiling or floor as government isn't directly affecting the price with their policy

3) The government has instituted a legal minimum price of $3.40 per gallon for gasoline. This is an example of price floor and is binding. The reason it is a price floor is because the petrol stations cannot charge a price below $3.40 but can charge any price above the floor price of $3.40
