How far does $1 go in the Dominican Republic?

Could you elaborate on the purchasing power of one dollar in the Dominican Republic? I'm curious to understand how far that small amount of money would stretch in terms of daily necessities like food, transportation, and perhaps even some basic entertainment. Is it a considerable amount for the local population, or does it barely make a dent? What kind of goods and services could one expect to acquire with just a single dollar in this tropical nation?
