Part 2 : a local pizzeria sold 72 pizzas yesterday. suppose the actual number of pizzas sold was 77. determine if the number of pizzas sold as a percent increase or decrease as compared to the amount sold yesterday, rounded to the nearest tenth. show your work.

6.9% increase

Step-by-step explanation: original: 72

                                              new: 77          5              x         =     500    = 6.9%

                                                                      72           100               72

the answer is 28

step-by-step explanation:

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.
