bill was $13.27. How much was the
total bill after the discount?

Step-by-step explanation:

To solve this you have to do this:

13.27/x (x being the discount ) x 15% = 11.2795

The answer is 11.2795

:)

i'm not sure i quite understand, could you provide more information?

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.
