Management gets two numbers (price and quantity) from one decision because

a. the demand curve consists of price and quantity pairs.
b. producers use both technical and financial information.
c. the average cost curve has only one low point.
d. the marginal utility of goods is fixed.

a. the demand curve consist of price and quantity pairs.

Explanation:

The amount of goods or services a consumer is willing to buy at specific price is one critical information to firm. Price and quantity demanded at particular points are mutually dependent on each other and information will be of no use if one it's available without the other because demand curve consist of price and quantity pairs and this is why the management gets price and quantity from one decision.

Not because producers uses both financial and technical information nor average cost has only one low point and morever marginal utilities of goods can vary.
