Lenicia is a waitress and just received $12.45 for a tip for a meal that cost $56.75. is the percentage of her tip above or below the standard 15%?

above 15%
below 15%

First, we have to know how much percentage the tip is from the meal cost. So,

($12.45 ÷ $56.75 ) * 100 = 21.94%

Thus, it is above the standard 15%. It is a good day for Lenicia! Keep it coming :)

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.
