A town with a once popular but now polluted lake takes steps to halt the flow phosphates from agricultural runoff into its public lake. Once the inflow of the pollutant is eliminated, the level of pollution in the lake declines at a rate of 5.5% per month through processes of sedimentation and outflow of water from the lake. If the equilibrium level of phosphate pollution in the lake was 2900 metric tons before the inflow of pollution was stopped, how much phosphate pollution remains in the lake after 3 years? Round your answer to the nearest 10 metric tons. Hint: Note that the time step in this problem is 1 month
