Question

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 that $40. what inequality shows the possible labor costs, L?

Answer 1

we must indicate that the sum between tha parts and labor must be less or equal than to 40

so

$P+L\le40$

where P is the value of Parts and L the value of Labor

we can replace P and solve L

$\begin{gathered} 17.50+L\le40 \\ L\le40-17.50 \\ L\le22.50 \end{gathered}$

this tells us that the value of the labor must be less or equal than $22.50

the inequality is

$L\le22.50$
