Answer:
Step-by-step explanation:
We have the following quadratic equation
The factored expression will have the following form
Where b and c are two real numbers which when added together result in -1, and multiplying them results in -20
You can verify that the numbers that meet this condition are:
-5 and 4
Then the factors are:
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.
