If the 11th worker hired by a firm increases that firm's output from 80 units to 90 units; and, the firm can sell the units for $40 each. What is the highest wage that the 11th worker will receive?

Title:

Step-by-step explanation:

Due to the joining of the 11th worker, the firm's output increases 10 units.

The price of each unit is $40.

The price of 10 units are .

The worker's wage will be highest if he will be paid all the amount which is the resultant of the output's increase, that is (90 - 80) = 10 units.

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.
