A. Make an overestimate and an underestimate of the total quantity of pollutants that escape during the first month.
overestimate =
functionsequation editor tons
underestimate = functionsequation editor tons
B. Make an overestimate and an underestimate of the total quantity of pollutants that escape for the whole six months for which we have data.
overestimate =
functionsequation editor
underestimate = functionsequation editor
