Respuesta :

We are told that the cost of printer paper is $10 and the cost of lines paper is $12 if the total cost is $490 we can express that mathematically as:

[tex]12l+10p=490[/tex]

We are also told that the total number of paper is 45 reams, this can be expressed mathematically as:

[tex]l+p=45[/tex]

Therfore, the system of equations is:

[tex]\begin{gathered} l+p=45,(1) \\ 12l+10p=490,(2) \end{gathered}[/tex]
