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.
__g +__ m= __
g + m = 19
are you sure
Apologies for the incorrect response earlier.
The correct system of equations is:
0.25p + 0.75m = 11.50
p + m = 19
The system of equations that could be used to solve for the number of pens, p, and the number of markers, m, bought is:
0.25p + 0.75m = 11.50
p + m = 19
Where p represents the number of pens and m represents the number of markers.
To write the system of equations, let's use the given information:
1. The total number of pens and markers is 19, so the equation for the quantity is:
p + m = 19
2. The total cost of the pens and markers is $11.50, so we can use the cost equation to find the relationship between the number of pens and markers:
0.25p + 0.75m = 11.50
Therefore, the system of equations is:
p + m = 19
0.25p + 0.75m = 11.50
