> For example, Carrefour said a bottle of sugar-free peach-flavoured Lipton iced tea, produced by PepsiCo, shrank to 1.25 litres (0.33 gallon) from 1.5 litres, resulting in a 40% effective increase in the price a litre.
That's only a 20% -- rather than 40% -- effective increase in the price-per-volume, right?
Trying to figure out what went on there. For example, maybe they meant that the price-per-volume did go up 40%, and they meant that the reduced-size contributed to (rather than "resulted in") that 40% increase? Or, maybe ChatGPT did the math?
