The system of equations could be:
p + m = 19
0.25p + 0.75m = 11.50
not including tax, a total of 19 pens and markers cost $11.50. the pens cost $0.25 each, and the markers cost $0.75 each. write the system of equations that could be used to solve for the number of pens, p, and the number of markers, m, bought.
p+m=_
_p+_m=_
