Afile cabinet with an original price of $50 is on sale for $35. by what percent did the price change?

30%

Explanation:

The answer is 30% because if you do 35 divided by 50 equals 0.7. That leaves 0.3 left over from one. The number 1 represents 100% therefore 70% of 50 is 35 which means that the price changes by 30%
