Problema Solution
The amount P of pollution varies directly with the population N of people.City A has a population of 442,000 and produces 260,000 tons of pollutants. Find how many tons of pollution we should expect City B to produce, if we know that it's population is 350,000
Answer provided by our tutors
P = kN
plugging in,
260,000 = k*442,000
so k = 260/442
plugging in,
P = [260/442]*350,000
= 205,882 tons
