7)Soil near a local chemical plant has become polluted. The current concentrations of mercury in the soil is 1085 ug/kg, while the acceptable limit is only 100 ug/kg. Cleanup efforts result in removing mercury form the soil, reducing the concentration of mercury. The differential equation that governs . the concentration C of the mercury in the soil as a function of time (in weeks) is given by: dC +0.02C= -80 di
