To have at least 20 pencils left in the box, even after giving away 15% of the pencils, you would need to calculate the original number of pencils using the formula:
x - 15% = 20
Rearranging the equation:
x = 20 / (1 - 0.15)
Simplifying:
x = 20 / 0.85
x ≈ 23.53
Therefore, you would have needed originally around 23 or 24 pencils in your box.
