Question

Thanks to its environmental initiatives, Lexington has cut its annual CO2 emissions by 10%. This year, the town produced 280,000 metric tons of emissions. If the downward trend continues, how much CO2 will be produced 2 years from now

Answer 1

Answer:

Explanation:

Rate = 10%

Time = 2 years

Initial CO2 = 280000 metric ton

1st year

10% × 280000

= 28000 metric ton.

2nd year

10% × (280000 - 28000)

= 25200 metric ton.

Metric ton of CO2 produced at the end of the 2nd year = 252000 - 25200

= 226800 metric ton of CO2.
