Suponha que, em sua empresa familiar,
Dona Joana vende um salgadinho a x reais
(por unidade). A quantidade vendida por dia
diminui com o preço e é dada por 32 – x.
Portanto, a equação quadrática
x (32 – x) = 31
significa que, com o preço x, o total
apurado nas vendas, isto é, a receita, é igual
a 31 reais por dia.
Qual o menor preço X do salgadinho para
que isto ocorra?
