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

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
