Question

Suppose that an elementary school starts a recycling program. After one year, the school has
reduced its trash from 144,000 pounds per year to 122,400 pounds per year. Find the percent
decrease in the amount of trash.

Answer 1

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%
