y = Mx + b
Kakashi and Obito get to school barely on time, they take their seats just as the teacher walks in. Rin waves at them but Obito seems distracted, for almost the whole morning Kakashi elbows Obito and nods towards Rin. Obito throws her the peace sign, he starts paying a little more attention to the teacher, even when lunch came around he was making faces that had started to get on Kakashi's nerves. Rin makes a face at Kakashi who gives out an annoyed sigh. Kakashi smacks Obito while Rin folds her arms. She knew that smile he gave her was trouble,
“whatever you're planning, don’t do it.” “Oh get off it, it's nothing bad, I was just wondering how many packets of jello it would take to fill up a large pool?.”
Kakashi looked over from where he was eating. “Jello?” he said in a flat voice
“a pool?” asked Rin
“Yep!” chirps a smiling Obito
Kakashi narrowed his eyes, Rin looked thoughtful. “ well…. I guess it would depend on how big the pool is. If it's a large pool it's about 2,500,000 L assuming a normal depth of 2 m. Thus making it 2,500 m^3.” obito just stared at Rin
“How do you even know that?” Exclaimed Obito
Rin just smiled
Kakashi was back to looking bored. “It takes 300mL of water to make 1 box of jello”
Obito grins that means it takes 4 boxes to make 1 liter
“No” Rin says “that’s 1200mL of water that’s more than just a liter”
“Huh?”
Kakashi groans “ok listen well I’m only explaining this once. A large pool is 2,500,000L, 1 packet takes 300mL that’s 0.300L of water, therefore you take the 2,500,000 L and divide it by the 0.300L to get how many packets are needed.”
Obito nods “Ok awesome” he looks at kakashi expectedly.
“That’s 8,333,334 boxes of jello” dead pans Kakashi
“Nooo!!!! That’s so many, I’d never afford that amount, even if I used the sugar free kind” wailed Obito
Rin giggles and goes back to eating her lunch
