Answer :
Final answer:
The percent decrease in the amount of trash is 15%. To find the percent decrease in the amount of trash, we need to calculate the difference between the initial amount and the final amount, and then divide it by the initial amount.
Explanation:
To find the percent decrease in the amount of trash, we need to calculate the difference between the initial amount and the final amount, and then divide it by the initial amount.
The initial amount of trash is 144,000 pounds per year, and the final amount is 122,400 pounds per year.
Therefore, the decrease in the amount of trash is 144,000 - 122,400 = 21,600 pounds per year.
To calculate the percent decrease, we divide the decrease by the initial amount and multiply by 100:
Percent decrease = (21,600 / 144,000) * 100 = 15%.
Answer:
15% is reduced
Step-by-step explanation:
I always start by finding what 10% and 5% is, after that, I try to see how I can make that into the number subtracted and for this it happened to be 15% I found that 10% was 14,400 and 5% was 7,200 and I found the total amount reduced was 21,600 which is 14,400+7,200 or 10%+5%
