Question 29935
Let the paper be x
Let the compass be 2x
Eraser = 3(2x)
Pencil = 6x/2


Total:
*[tex x+2x+6x+6x/2=1.80]
{{{2(x/1)+2(2x/1)+2(6x/1)+2(6x/2)=2(1.8/1)}}}
*[tex 2x+4x+12x+6x=3.6]
*[tex 24x=3.6]
x=0.15 (paper)

2(0.15)=0.3 (compass)


3(0.3)=0.9 (eraser)


6(0.15)/2=0.45 (pencil)


Hence, the paper is for $0.15, a pencil is for $0.45, a eraser is for $0.9 and a compass is for $0.3
