step-by-step explanation:

the sale price is (1.00 - 0.77)($87), or 0.23($87), or $20.01.

b: |12 – x| ≤ 0.25

step-by-step explanation:

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.
