Let's assign variables to the unknown quantities: let p be the number of pens and m be the number of markers.
The first equation relates the total number of pens and markers to the total cost:
0.25p + 0.75m = 11.50
The second equation simply states that the number of pens and markers bought is equal to 19:
p + m = 19
So, the system of equations is:
0.25p + 0.75m = 11.50
p + m = 19
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.(4 points)%0D%0APut responses in the correct input to answer the question.
