Answer:
![\\E(t) =40(0.65)^{t}](https://tex.z-dn.net/?f=%5C%5CE%28t%29%20%3D40%280.65%29%5E%7Bt%7D)
Step-by-step explanation:
Since the country wants to reduce the emission by the percentage each year, the function will be decaying function. The formula of decaying function will look like this
![E(t) =E_{0} (1-r)^{t}\\](https://tex.z-dn.net/?f=E%28t%29%20%3DE_%7B0%7D%20%281-r%29%5E%7Bt%7D%5C%5C)
Where
E(t) = the number of emission after t years
E0= the number of initial emission= 40 million tons
r=rate of growth/decay = 35%= 0.35
t= time in years
If we put the number, the equation will be:
![E(t) =E_{0} (1-r)^{t}\\E(t) =40(1-0.35)^{t}\\E(t) =40(0.65)^{t}](https://tex.z-dn.net/?f=E%28t%29%20%3DE_%7B0%7D%20%281-r%29%5E%7Bt%7D%5C%5CE%28t%29%20%3D40%281-0.35%29%5E%7Bt%7D%5C%5CE%28t%29%20%3D40%280.65%29%5E%7Bt%7D)
