Question 461048
The number of N of aluminum cans can be used each year varies directly as the numbr of people P using the cans.
 If 53 people use 11,342 cans in one year, how many cans are used in a city which has a population of 1,518,000?.
 The answer I have is: 324,852,000 is that correct?
:
Let's see
{{{53/1518000}}} = {{{11342/c}}}
Cross multiply
53c = 1518000*11342
c = {{{1.722(10^10)/53}}}
c = 324,852,000, so you are absolutely right!
