Katy bought some markers for 3$ each, and a notebook for $5. Katy did not spend more that $17. Which inequality can be used to find y, the number of markers that Katy could of had bought?

Respuesta :

Katy bought ''y'' markers for 3$ each.

And a notebook for $5.

Katy has to spend $17 or less, then the symbol for the situation would be (≤)

[tex]3y+5\leq17[/tex]

Solve for y:

*As a first step subtract 5 from both sides of the inequality:

[tex]\begin{gathered} 3y+5-5\leq17-5 \\ 3y\leq12 \end{gathered}[/tex]

Then, divide both sides by 3.

[tex]\begin{gathered} \frac{3}{3}y\leq\frac{12}{3} \\ y\leq4 \end{gathered}[/tex]

Katy could buy 4 or fewer markers.
