Question 1107417: Al got an estimate for repairs on his bike. The
parts will cost $17.50, and the parts and labor
together will not be more than $40. Which
inequality shows the possible labor costs, L?

You can put this solution on YOUR website!
total cost is parts and labor.

the total cost will not be more than 40 dollars.

this means it will be less than or equal to 40 dollars.

let L = the labor costs.

your equation becomes 17.50 + L <= 40

subtract 17.50 from both sides of this equation to get L <= 40 - 17.50

solve for L to get L <= 22.50.

when labor is less than or equal to 22.50, the total cost will be less than or equal to 17.50 + 22.50 which makes it less than or equal to 40.
