Acesso em:.https://bdm.ufpa.br/handle/prefix/4446The study describes about the commercialization of fish in the municipal fair of Abaetetuba with the use of the affine function, seeking to evaluate 04 species of fish most commercialized in this fair. Two weekly visits were made to the fair in May 2022, with the participation of a balancer who sells the fish with the fishmongers who sell the fish in the municipal market. First, we sought to understand the values of the fish that the balancer sells and after collecting these data, we sought to know the values of the fish marketed by the fishmongers. Of the different species sold, the research focused on only 04 types of fish that are the most commercialized and consumed by the population of Abaetetubense. The white hake, the mapará, the gilthead and the cub were the species included in the research to study the profit obtained by the sale to both the balancer and the fishmonger who sell the product. The research is concluded considering that the sale of the marketed product has a greater profit for the balancer who sells a greater amount of fish during the week, while the fishmongers with a greater number acquire a lower profit with the sale of fish to the local population.Acesso AbertoBalanceiroPescadoPeixeiroComercialização e LucroBalancerFishFishmongerCommercialization and ProfitCNPQ::CIENCIAS EXATAS E DA TERRA::MATEMATICATrabalho de Curso - Graduação - Artigo
