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)

To set up the system of equations for the problem, we need to account for both the total cost and the total number of items bought.

  1. The first equation represents the total number of items (pens and markers): \[ p + m = 19 \]

  2. The second equation represents the total cost: \[ 0.25p + 0.75m = 11.50 \]

So the responses to fill in the system of equations are:

For the first equation: \[ p + m = 19 \]

This means you will input "19" in the response area for the first equation.

For the second equation, you didn't ask for an input, but it would be: \[ 0.25p + 0.75m = 11.50 \]

In summary, the correct input for your first equation is:

19
