Answer:

a) Q = 100M + 60C

b) L = 0

c) L = Q / 60

d) Cost = $66.67

Explanation:

a)

Let M be the self service machines and L be the cashiers hired by company.

M = self service machines

C = hired cashiers

Q = Total output

Each self service machine can process 100 orders per hour = 100M

Cashier can process 60 orders per hour = 60C

Then,

Q = 100M + 60C

b)

Marginal Product of self service machine = 100 / 20 = 5 order per dollar

Marginal Product of cashier = 60 / 10 = 6 order per dollar

Marginal Product of cashier is higher than Marginal Product of self service machine(6 > 5).

Then, demand for self service machine is zero.

L = 0

c)

L = Orders to be processed / Order processed per cashier  

L = Q / 60

d)

L = Q / 60

L = 400 / 60 = 6.66666667

Cost = L x 10 = 6.66666667 x 10 = $66.67

Hope this helps!

Answer:

D: Guests must pay for any alcoholic beverages

Explanation:

Guests in any establishment are expected to pay for any alcoholic beverages they consume. A private club is not necessary a profit-making venture, but a social or networking establishment. Membership to a private club is restricted. Members usually pay a membership to join and a regular subscription fee.

The club purchases foods and drinks served in its premises. The food and beverages are sold to members at fair prices. Members are required to pay for what they consume. Many clubs do not charge a service fee as it is catered for in the recurring subscription fees.

katovenus [111]

Answer:

If the Fed conducts an open market purchase by specifically buying government securities from the Bank, banks' reserves increase and the quantity of money increases.

Explanation:

The Federal Reserve (Fed) buys and sells government securities to control the money supply. This activity is called open market operations (OPO). By buying and selling government securities in the free market, the Fed can expand or contract the amount of money in the banking system and pursue its monetary policy.

To increase the money supply, the Fed will purchase bonds from banks to inject money into the banking system.

The Federal Reserve's latest effort to calm the financial system — pumping $100 billion a day into trillion-dollar funding markets — is intended to be a temporary role, born of necessity. But it may turn out to be a significant expansion of the Fed's footprint.
