Which expression represents decreasing a quantity by 35%?

Explanation:
Decreasing a quantity by 35% means you subtract 35% of the original amount from itself. 35% as a decimal is 0.35, so the amount after the decrease is x − 0.35x. This directly expresses taking away 0.35x from x, and it simplifies to 0.65x, showing the final value is 65% of the original. The other patterns subtract 0.30x, 0.40x, or 0.50x, which correspond to decreases of 30%, 40%, and 50% respectively, not 35%.
