QUICK SOLVE a radio station has three types of promotional items: cds, hats and flying discs. cds are worth $4.50, hats are worth $3.25 and flying discs are worth $1.25. they have given away 11 cds, 26 hats and 53 flying discs. organize the information using matrices. then use matrix multiplication to find the station's total cost for promotional items.

write matrix equation and solve it by hand.

edit: bump, please answer!

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

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.
