The cake store is having a 25\%25% off sale on all of its cakes. if the cake you want regularly costs \$9$9, how much would you save with the discount?

You would save $2.25.  

Step-by-step explanation:

In order to find discount on an item, you need to multiply the discount by the original amount of the item.  In this case, the cake you want regularly costs $9.  If the sale includes a 25% discount, then you need to first convert your percentage to a decimal by dividing by 100:

You can then take this amount multiplied by the original cost of the cake to get your discount:

0.25 x 9 = 2.25, so you would save $2.25 with the discount and pay only $6.75 for the cake you want.  

14

step-by-step explanation:

14 x 3 = 42

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.
