The Environmental Protection Agency (EPA) determines that Maple Lake has 250 tons of pollutant as a result of industrial waste and that 10% of the pollutant present is neutralized by solar oxidation every year. The EPA imposes new pollution control laws that result in 15 tons of new pollutant entering the lake each year. The amount of pollutant in the lake after n years is given by the recursively defined sequence 

p₀ = 250, p_n 0.9p_n-1 + 15

Determine the amount of pollutant in the lake after 2 years. That is, determine p_2.
