A drone costs $300 plus $25 for each set of extra propellers. What is the cost of a drone and 4 extra sets of propellers? (a) Write a function that will show the cost.

300+(25×4)= 400

Step-by-step explanation:

It just does

ian gonna lie that is way to much

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.
