Four key marketing decision options are price (P), advertising (A), transportation (T), and product quality (Q). Consumer demand (D) is influenced by these variables. The simplest model for describing demand in terms of these variables is

D= k-pP + aA + tT +qQ

Explanation:

The simplest model for describing demand in terms of these variables will be given as D= k-pP + aA + tT +qQ

where,

D = Consumer demand

P = Price

A = Advertising

T = Transportation

Q = Product quality

Based on the model, when there's a rise in the price, there'll be a reduction in the demand while when there is an increase in advertisment, product quality and transportation, this will bring about an increase in the demand.

The simplest model for describing demand in terms of these variables is D= k-pP + aA + tT +qQ

The following information should be considered:

D= k-pP + aA + tT +qQ

Here

D = Consumer demand

P = Price

A = Advertising

T = Transportation

Q = Product quality
