Therefore, the first thing to understand is the percentage of inflation that affects your country, there are "normal" percentages, others fluctuate, and the worst of all is the one where you live with an inflationary economy. In any of them, as a citizen you cannot do anything to change these situations, governments and private companies must do them, that is a priority, since that is where you can begin to take basic ideas to face price changes.
