Find examples of grocery item prices in a newspaper, on television, or on the internet. conpare unit prices of two different brands of the same item. explain which item it the better buy

You can choose any two items and find the unit price for both.

1. Lets say we have a cereal box of brand ABC of 500 grams priced at $10.

So, we can find the unit price as:

per gram will cost = = 0.02 dollars per gram

2. Lets say we have a cereal box of brand XYZ of 500 grams priced at $13.50.

per gram will cost = = 0.027 dollars per gram

We can compare that per gram of cereal is costly for XYZ brand.

Hence, based on price alone, we can consider buying cereal from brand ABC.

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.

step-by-step explanation:

the radius is 2 times the diameter.
