Nacir is buying school supplies. He purchases 8 notebooks for $12.48.How much does Nacir pay for 1 notebook?Drag and drop the answer into the box.

Answer 1

If Nacir purchases 8 notebooks for $12.48, let the amount Nacir pays for 1 book be represented as y.

This implies that

`\begin{gathered} 8\text{ notebooks }\Rightarrow\$\text{ 12.48} \\ 1\text{ notebook }\Rightarrow\text{ y} \end{gathered}`

By cross-multiplication, we have

`y*8\text{ notebooks = \$12.48}*1\text{ notebook}`

Divide both sides of the equation by 8 notebooks.

Thus,

`\begin{gathered} \frac{y*8\text{ notebooks}}{8\text{ notebooks}}\text{ = }\frac{\text{\$12.48}*1\text{ notebook}}{8\text{ notebooks}} \\ \Rightarrow y=\$1.56 \end{gathered}`

Hence, Nacir
