The Kelley School is having its annual Holiday Fair. Items are sold for either 25 cents or 50 cents. Each child in our class can spend $2.00 at the fair. Assuming that every child spends all of her/his money, how many 25-cent and 50-cent gifts could have been bought altogether by our class of 11 students? Note: All gifts are purchased with either quarters or 50-cent pieces!

You can buy 8  0.25 cent items because 0.25 · 8 = 2

you can buy 4  0.50 because 4 makes 2 dollars

you then multiply for the 11 students

what?

step-by-step explanation:

what do you need with. i love quadrants. can you tell me ?

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.
