Question

aluminum production from bauxite ore costs $2000 per ton, whereas aluminum recycling costs $800 per ton. what is the percent saved by recycling?

Answer 1

Answer: 40%

Step-by-step explanation: $2000

If you turn the 2000 into 20 (for now) and the 800 into 8, then the 20 into 10, and the 8 into 4, then 4 out of 10 equals 40%.
