Boxes of cereal normally cost £2.89 each, but a supermarket has a special offer: Boxes of Cereal
3 for the price of 2

Megan has £20 and she wants to get as many boxes of cereal as possible.

How many boxes can she buy?

10 boxes

Step-by-step explanation:

- 2.89*2= 5.78

20/5.78= 3.4...

which means you can spend 5.78 (the cost of two boxes) three times. now. if they're selling the boxes 3 for the price of two, you're actually getting 3*3.4 for your total amount you can purchase.  3*3.4= 10.2 obviously you can't get .2 boxes of cereal, so you round down to get 10 total boxes of cereal.

answer: i guess 5 units?

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.
