Explanation Given: To solve the underground water contamination problem the city of Manchester has built a municipal sewer and many homeworkers would like to have sewer lines connected to their homes. Each year the number of homeworkers who use the private septic tanks will decrease by 8%. The city feels that the problem of underground water contamination can be solved when the number of houseworkers will be less than 10% in 25 years. Formula used: An exponential function can be used to solve compound interest exercises with principle, rate r and time t is given by, A = P ( 1 + r ) t Calculation: Since, it is provided that each year the number of homeowners who use private septic tanks decrease by 8% percent. Now, since an exponential function can be used to solve compound interest exercises with principle, rate r and time t is given by, A = P ( 1 + r ) t The same equation can be used to find the percentage of homeworkers who will still use private septic tanks in 5 years. Since, 8 percent of homeowners are decreased every year, so r = − 0.08 . And, initially, let all the homeowners used private septic tanks, then P = 1 . Thus, the equation, A = P ( 1 + r ) t will become, S = ( 1 − 0.08 ) t Now, to find the percentage of homeworkers who will still use private septic tanks in 5 years
