What is the approximate percent change in a temperature then went down from 120ﾟ to 100ﾟ the person changes approximately 17% the percent change is approximately 20% the percent change is approximately 80% the percent change is approximately 120

The answer is 17%

explanation:

One way to find percents is to multiply the number you're trying to find the percent of (120) by whatever percent you're looking for (0.17, 0.2, 0.8, etc) If you multiply 120*0.17, you'll get about 20, which is how much was the amount of degrees lost.

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
