Question

One aluminum can weighs about 1/25 lb. if your school starts a recycling drive, how many cans will your school me to collect to recycle one ton?

Answer 1

50,000 cans
because if 1 can = 1/25 lb
the 25 cans = 1lb
and 1 ton =2,000lbs
so 25x2,000=50,000

Answer 2

1 ton=2000lb
total weight=2000
we want total weight=weight of cans
weight of cans=weight of 1 can times number of cans
W of cans=1/25c

total weight=weight of cans
2000=1/25c
times 25/1 both sides
50000=c


50,000 cans
