Autor: Maurício Munhoz | Publicado: 2012-07-08T15:00:00-03:00


Agora estamos praticamente concluindo o nosso trabalho. Vamos ao cálculo da porcentagem.
Primeiramente temos que lembrar que já calculamos o preço dos ingrediente e já preenchemos a tabela.
Você já deve ter somado o preço de todos os ingredientes ? Certo, se já fez isso podemos continuar.
O total dos preços dos ingredientes vai ser o nosso 100% do trabalho, essa conclusão é essencial para que possamos calcular as porcentagens.

Vamos ao nosso exemplo do Bolo de chocolate.
Lembrando dos cálculos dos ingredientes e da tabela já construída.
Os cálculos dos ingredientes
