Answer:

2880 cans.

Step-by-step explanation:

Currently, he already collected 1,100 pounds of newspaper.

Each pound is equal to one penny or 0.01 dollars.

1100 * 0.01 = $11 dollars.

$20 - $11 = $9.

He needs $9 dollars.


$9 / 0.05 (Nickel value) = He needs 180 Nickels / Pounds of Aluminum.

180 pounds = 2880 oz (180 * 16)

He needs 2880 cans.
