Answer:

Craft paper = $1.75

Box of markers = $3.60

Glue Sticks = $0.95

Step-by-step explanation:

x = craft paper

y = box of markers

z = glue stick

Jesse's purchase = 3x + 4y + 5z = 24.40

Maria's purchase = 6x + 5y + 2z = 30.40

Charles' purchase = 3x + 2y + z = 13.40

Solve the system of equations:

(x, y, z) = (1.75, 3.6, 0.95)
