Question

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 expect City B to produce, if we know that its population is 362,000?

Answer 1

Set this up as a proportion:

 

494,000 people → 260,000 tons

362,000 people → P tons

 

P = (362,000 x 260,000) / 494,000 ≅ 190,526 tons
