The number of aluminum cans used each year varies directly as the number of people using the cans. If 225 people use 60,000 cans in one year, how many cans are used each year in Nashville, which has a population of 691,243?

let c be the number of cans people used, p be the number of people and k be the constant of proportionality
:
a) the number of cans used by people equals the product of the number of people and the constant of proportionality
:
b) c = p * k
:
c) 60000 = 225 * k
:
k = 60000/225 = 4000/15 = 800/3
:
c = 691243 * (800/3) = 184331466.67 is approximately 184,331,467
:
d) The population of people in Nashville used 184,331,467 cans in a year
