This is just like the question I helped you with earlier, but you have to combine them together, what do you think?

\[y=mx+b\] where \(m\) is the rate of change and \(b\) is the initial value

Well, it isn't B, because you don't subtract values in this equation, so?

@UnkleRhaukus : I think at Ramiro's age, formulas like that are more confusing that actually using real life examples. Granted, I'm under the impression that Ramiro doesn't care either way, so it probably doesn't matter.
