<u>B. shows planned purchase rates of goods and services at various price levels.</u>

Explanation:

  • The aggregate demand is the total demand for final goods and services in the economy over a given period of time. And is often distinguished as the effective demand curve. That is the demand for the GDP of the nation.
  • As it specifies all the goods and the services that are to be purchased at all the possible levels. Hence this demand curve shows us the real output given on the horizontal axis. Thus the curve shows the quantity of the output that is demanded and the aggregate of the all price level.

A monopolist faces a demand curve given by: P = 105 – 3Q, where P is the price of the good and Q is the quantity demanded. The m
geniusboy [140]

Answer: 15

Explanation:

For profit to be maximized by a monopolist, the marginal revenue and marginal cost must be gotten.

P= 105-3Q

MC= 15

Since total revenue is price × quantity, TR= P×Q = (105-3Q)Q

= 105Q-3Q^2

MR= 105-6Q

Since we've gotten marginal revenue and marginal cost, we equate both together.

MR=MC

105-6Q = 15

6Q = 105-15

6Q=90

Divide both side by 6

6Q/6 = 90/6

Q= 15

The quantity that will maximise profit is 15
