Answer:
let x be the Robert piece
y Maria's piece
x+y=10
0,5*x ( half of Robert piece)= 2/3 y( 2 thirds)
2 equations then
x+y= 10 then x= 10-y
0,5x= 0,67 y then we replace x by 10-y on the second equation and it gives
0,5(10-y)= 5-0,5y=0,67y
5= 1,17 y so y= 4,27 and then x= 10-y= 5,73
the question asks how much Robert wire is longer than Maria's wire
so we get x-y= 1,46
This is the table=
A B
1 3.5 3.75
40 140 150
100 350 375
so more cheaper is printer A
Sum=14 + 37 + 22 + 56 + 33 = 152 => 100%
red = 14 => x%
100% / 152 = x / 14
x = 100 × 14 / 152
x = 1400 / 152
x = 9,21% = 9%
