Question 533748: A marker cost as much as 4 pens. Manny paid $143 for 2 markers and 5 pens. What is the cost of a marker? What is the cost of a pen? Answer by unlockmath(1688) (Show Source):
You can put this solution on YOUR website! Hello,
It's unreal that it would cost $143 but here's how to solve it.
Let x be the marker and y represent the pens.
4y=x
2x+5y=143
Solve by substitution:
4y+5y=143
Combine like terms and divide by 143 to get:
y=$15.89 (rounded off) for a pen.
x=$63.56 (Rounded off) for a marker.
