Calculate the Weight of the Green Notepad
Now, let’s move to the second scale in the middle.
This time, we see two different objects placed together: one yellow pencil and one green spiral notepad.
The display shows a combined weight of 350 units.
We already know that one pencil weighs 50 units, so we do not need to start from zero.
All we have to do is subtract the pencil’s weight from the total displayed on the scale.
Calculation:
350 − 50 = 300
Therefore, the green spiral notepad weighs 300 units.
