Question

Consider that recycling an aluminum can only requires 6% of the energy needed to make the can in the first place. Given that the energy saved by recycling the can will result in enough energy to run a 100W TV for 3 hours. How much energy does it take to make 19 Aluminum cans

Answer 1

21829787.23 joules

Explanation:

The recycling will require 6%energy if initial energy, let's say x.

94% of x will be used to power a 100W TV for 3 hours

X = (100*3*60*60)/0.94

X = 1148936.17 joules.

To make 19 aluminum cans ,

It will take 1148936.17*19

= 21829787.23 joules
