In much of the country, homeowners choose to heat their houses with either natural gas or heating oil, both of which are normal goods. Which factor would cause an increase in the demand for natural gas

Group of answer choices.

a. an increase in consumer incomes

b. an increase in the price of natural gas

c. a decrease in the price of heating oil

d. a decrease in the price of natural gas

a. an increase in consumer incomes

Explanation:

A market demand curve is used to graphically represent the quantity of goods demanded by all the buyers or consumers at different price points.

This ultimately implies that, a market demand curve can be determined by the horizontal summation of the various quantities for which, each buyer or consumer in a market is willing to pay for at different prices.

Thus, the market demand curve is downward sloping due to the fact that as the price of a product increases, the quantity demanded by the consumer decreases.

Generally, the demand for a good or service increases when consumer income increases and it decreases when the income earned by consumers fall. Thus, the demand for goods or services is directly proportional to consumer income.

Hence, a factor which would cause an increase in the demand for natural gas is an increase in consumer incomes.
