Respuesta :

We know that

• The total is $90.

,

• Each pen costs $0.75.

,

• Each pencil costs $0.15.

,

• x represents pens, and y represents pencils.

Based on the given information, the expression is

[tex]0.75x+0.15y=90[/tex]

The greatest number of pencils would be 100.

The greatest number of pens would be 100.

Since these values satisfy the equation

[tex]\begin{gathered} 0.75(100)+0.15(100)=90 \\ 75+15=90 \\ 90=90 \end{gathered}[/tex]

Therefore, they can buy 100 pens and 100 pencils.
