At the toy store, 3 toy cars cost $2.82. How much does it cost to buy 30 toy cars?

$28.20

Step-by-step explanation:

First, find out how much 1 toy car costs by dividing the cost for 3 by the price:

Each toy car costs $0.94. Multiply the price for one car by 30:

The cost for 30 toy cars at the price of $0.94 each is $28.20.

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.
