Karen paid $1.20 for 6 pencils and 4 erasers at the school store. Trey paid $1.10 for 8 pencils and 2 erasers at the same store. Given that x represents the cost of a pencil in dollars and y represents the cost of an eraser in dollars: Christine says the system representing the situation should be: 1.20(6) + 4y = x 1.10(8) + 2y = x Michele says the systems should be: 6x + 4y = 1.20 8x + 2y = 1.10
