Question

Monique had $34 to spend on art supplies. After buying a sketchbook for $13.50, she purchased 4 charcoal pencils each for the same price. She had $11.30 left in change. How much is each charcoal pencil?

Answer 1

She had a total of $34 to spend on art supplies.

She purchased a sketchbook for $13.5 and 4 charcoal pencils each one for the same x price.

She had $11.30 left in change.

With the situation above, we can create the following equations:

Let x be the price of each charcoal pencil

`\begin{gathered} 13.5+4x+11.30=34 \\ 4x+24.8=34 \\ 4x=34-24.8 \\ x=(9.2)/(4) \\ x=2.3 \end{gathered}`

Each charoal pencil costs $2.3.
