Answer: The nominal money supply should set at 1,600.
Explanation:
Given that,
Money demand function: (M/P)d = 2,200 – 200r
r - Interest rate
Money supply (M) = 2,000
Price level (P) = 2
If the fed wants to set the interest rate at 7% then,
Money supply = money demand
= 
= 2,200 – 200r
P = 2 and r = 7%
= 2,200 – 200 × 7
M = 800 × 2
M = 1,600
The nominal money supply should set at 1,600.
Answer:
C. a derived demand.
Explanation:
Derived demand is a rise in the demand of a product due to the increase in demand for related or intermediate goods. If two distinct goods or services are used together, a rise in the demand of one will cause the demand for the other to rise. Products or services used together are called complementary goods.
Derived demand is primarily as a result of the usage of a product in the production or consumption of other goods or services. In this case, the demand for workers is solely due to a rise in the demand for cars. Should the demand for vehicles decrease, then the demand for workers will fall.
