Company 1 says that they will complete the job for $12 per foot of fencing. Company 2 says that they will charge you $250 for the first 100 feet of fencing and $15 for each additional foot. Determine the cost of fencing for both companies.

Results are below.

Step-by-step explanation:

Giving the following information:

Company 1:

Variable cost= $12 per foot

Company 2:

Fixed cost= $250

Variable cost= $15 per foot

To determine the total cost of each company, we need to use the following formulas:

Company 1:

Total cost= 12x

x= number of feet

Company 2:

Total cost= 250 + 15x

x= number of feet

For example, for 150 feet:

Company 1:

Total cost= 12*150= $1,800

Company 2:

Total cost= 250 + 15*(150 - 100)

Total cost= $1,000

the discriminant is 64 + 4*1*12 = 112

this is prime.
