You can put this solution on YOUR website! Hi there,
The amount of pollution varies directly
with the population of a city.
Poll = kPop
Find k the constant of proportionality
260,000 = k442,000
k = 260,000/442,000
k = 0.588 (3 decimal places)
Formula:
Poll = 0.588Pop
Calculation:
Poll = 0.588 x 344,000
Poll = 202,272tons
Hope this helps :-)
