Correction of problem submiited earlier.
The amount P of pollution varies directly with the population N of people. City A has a population of 494,000 and produces 260,000 tons of pollutants. Find how many tons of pollution we should except City B to produce if population is 344,000. Do not round until final answer, then round to nearest ton as needed

  • math -

    Is "except" supposed to be "expect".

    OK, so P = C N where C is a constant
    This implies
    Pb/Pa = Nb/Na

    The subcripts denote cities A or B

    Pb = Pa*(Nb/Na)
    = 260,000*(344/494)= 181,053 tons

  • math -

    it is expect. thanks
