Let us take the case of United Building Company First
Rate per square foot = $15.75
Conference fee taken per hour = $45.99
Total conferencing hours = 4 hours and 15 minutes
= 4.15 hours
Total square feet of the house = 12226 square feet
Then
The total cost taken by the company = (15.75 * 12226) + ( 45.99 * 4.15) dollars
= 192559.5 + 190.86 dollars
= 192750.36 dollars
So the total amount taken by United Building Company is $192750.36 dollars
Now let us take the case of American Contracting Company
Rate per square foot taken = $12.46
Flat conferencing fee taken = $230
Then
The total cost taken by the company = (12.46 * 12226) + 230
= 152335.96 + 230 dollars
= 152565.96 dollars
So the total cost taken by the American Contracting Company is $152565.96.
13500-1500= 12000/5=2400
12000-2400= 9600

πr2 is an example of a (D) model.
<h3>What exactly is a model?</h3>
- A mathematical model is a system description that makes use of mathematical concepts and language.
- The process of developing a mathematical model is known as mathematical modeling.
- Natural sciences (physics, biology, earth science, chemistry), engineering disciplines (computer science, electrical engineering), and non-physical structures such as the social sciences all use mathematical models (such as economics, psychology, sociology, and political science).
- The use of statistical equations to solve problems in business or military operations is a large part of the field of operations research.
- Mathematical models are used in music, linguistics, and philosophy (for example, intensively in analytic philosophy).
- A model is, for example, the πr2 method for calculating the area of a circle.
Therefore, πr2 is an example of a (D) model.
