Question

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?

Answer 1

5 (notebook) + 3x (markers) < $17

Explanation:

Answer 2

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 (≤)

`3y+5\leq17`

Solve for y:

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

`\begin{gathered} 3y+5-5\leq17-5 \\ 3y\leq12 \end{gathered}`

Then, divide both sides by 3.

`\begin{gathered} (3)/(3)y\leq(12)/(3) \\ y\leq4 \end{gathered}`

Katy could buy 4 or fewer markers.
