Your balance would be 35, I think
The 3 angles of a triangle equal 180.
Subtract the bottom 2 angles from 180 and you get 50
So 8x + 2 = 50
Subtract 2 from both sides:
8x = 48
Divide both sides by 8
X = 6
First you need to find out the remaining value after he bought the calculator this would be 14.67.
60.54 - 45.87= 14.67
Next youll assume the packs of notebooks all cost the same and divide by 3
14.67 / 3 = 4.89
He spent 4.89 on one pack of notebooks
