Charmaine's coffee shop makes a blend that is a mixture of two types of coffee. type a coffee costs charmaine $4.10 per pound, and type b coffee costs $5.70 per pound. this month's blend used twice as many pounds of type b coffee as type a, for a total cost of $465.00 . how many pounds of type a coffee were used?

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.
