Mohammad · Answer 1

35,000 * (.97) ^n

Step-by-step explanation:

This should be right because the starting value of 35,000 is on it's own, then you have the rate of decay, which is 1-.03 (We get this because to stay constant is one and decay takes the percent in decimal value away from one) to the power of n to signify that each year, the amount of pollution is reduced exponentially.
