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. which system of equations could be used to solve for the number of pens (p) and the number of markers (m) bought?

The system of equations would be:

p + m = 19

0.25p + 0.75m = 11.50

Step-by-step explanation:

To set up a system of equations, use the total number purchased as the first equation.

p + m = 19

Now use the cost and the total spent for the second equation.

0.25p + 0.75m = 11.50
