Part A: Janie charges $8 an hour to babysit with an additional flat fee of $15 for each babysitting job. she wants to purchase a new game system that will cost her $139.40. write an inequality to show the least number of complete ours needs to babysit the purchase the game system if she has one job scheduled. Part B: solve the inequality that you created in part a.

Janie is considering changing her rate to $12 an hour with no flat feet. What effect would this change have on our that Jenny needs to work to buy the gaming system?
What conclusions can you draw about Janie changing the flat fee and not charging the flat fee?

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.
