40. The concentration of a pollutant in the atmosphere increases according to the exponential growth model A= Pe", where time is measured in years and r=0.0035. In 1990, the concentration was 56 parts per million. Clean-up procedures will be initiated when the concentration reaches 70 parts per million. According to the model, in what year will that occur?
