You can put this solution on YOUR website! The number N of aluminum cans used each year varies directly as the number of people P using the cans. If 57 people use 16,473 cans in one year, how many cans are used in a city which has a population of 1,862,000?
-------------------------------
N = kP
Solve for "k" using "If 57 people use 16,473 cans in one year".
16,473 = k*57
k = 289
---
Equation:
N = 289/P
---
How many cans are used in a city which has a population of 1,862,000?
N = 289/1,862,000
---
N = 1.5521x10^-4
