Question

Robert collected 330 aluminum cans. If 100 aluminum cans weigh 4 pounds, and the recycling center is paying 25 cents a pound, how much will robert be paid for 330 cans?

Answer 1

First, determine the weight of 330 cans with the given conditions,
                    (330 cans) x (4 lbs / 100 cans) = 13.2 lbs
Then, the price is determined by multiplying this weight to the price that the recycling center is paying,
                         (13.2 lbs) x (25 cents / lb)  = 330 cents = $3.3
Thus, Robert will be paid $3.3.
