When I taught Personal Finance as an online class, I would post photos like this as extra credit opportunities during exams. The question would be something like this:
Assume that you went into this store and ordered the following:
- 1) exactly one gallon of Unleaded gasoline and
- 2) a single 2 Liter bottle of Pepsi.
- a) $3.38
- b) $3.39
- c) $3.389
- d) $2.4089
- e) none of the above
Also, hasn't the ship pretty much sailed on the whole 9/10ths of a cent for gasoline prices? Maybe that made sense (well, no, not really) back when prices were 35 cents per gallon. But why do we (they?) care about posting the 9/10ths of a cent when the price is two-fifty a gallon? Will they still do it when the price is five bucks a gallon? Ten bucks a gallon? Isn't this totally absurd? And will people ever learn the difference between the cents sign and the dollar sign? Am I takin' crazy pills here?
