Answer: 60%
This is because the shaded boxes cover 60/100 of the total boxes
-3|2x + 6| = -12
|2x + 6| = -12/-3 = 4
2x + 6 = 4 and 2x + 6 = -4
2x = 4 - 6 = -2 and 2x = -4 - 6 = -10
x = -2/2 = -1 and x = -10/2 = -5
x = -1 and x = -5
Option B is right that is hundreds block, 2 tens block and 4 ones block.
