So if you look at what it would cost if every state government invested in universal preschool at age four, full-day preschool at age four, the total annual national cost would be roughly 30 billion dollars.
Se olharmos para o que custaria se cada governo estatal investisse no pré-escolar universal a partir dos 4 anos, com carga horária integral, o custo anual nacional seria de cerca de 30 mil milhões de dólares.
