Inflation

  The value of a 25 fils coin decreases over time due to inflation. How far back (or forward) would we have to go for the average person to just “break even” in picking up the coin? How long until it is no longer worth it for the average person to pick up a 1 dirham coin? - How much money would Elon Musk have to see on the ground for it to be worth his time to pick up? (his income was estimated at $11B per year - you can pretend he has to spend time "working" to earn the money, even though I imagine it just falls into his bank account) -In your conclusion, it makes sense to talk about the limits of the work. In this case, what other factors (which you were asked to ignore) might be relevant to picking up a coin?
