Landfill

Calculus Level pending

At the beginning of 2010, a landfill had 1400 tons of solid waste. The increasing function $$W$$ models the total amount of solid waste stored at the landfill. Planners estimate that $$W$$ will satisfy the differential equation $$\dfrac{dW}{dt} = \dfrac{(W-300)}{25}$$ for the next 20 years. $$W$$ is measured in years from the start of 2010. What will be the amount of waste when $$t= 1$$ year?
