Let p be the number of pens bought and m be the number of markers bought. The total number of pens and markers bought is p + m = 19.

The total cost of all the pens and markers is 0.25p + 0.75m = 11.50.
So, the system of equations that could be used to solve for the number of pens and markers bought is:
p + m = 19
0.25p + 0.75m = 11.50
