Depends... is it an Iphone? Lol, just kidding.
So, for as long as he's been watching the NFL series on Cartoon Network, Joe has used 32% of his battery and he spent 4 hours watching TV. So, every 4 hours he spends watching TV, he uses 32% battery. You divide 4 by 32, and you should get 12.5. The original equation looks like this:
y = 4/0.32
Now you have 12.5 = 4/0.32.
Answer: Joe spends 12.5 hours of watching Rick and Morty if his battery was full.
Lol, I'm just random. Don't mind me.
