The consumer cost of a new car is the sum of the factory cost with the percentage of the distributor and with taxes, both applied to the cost of factory. It is known that the percentages are the same as in the following table. Make a program that receives the car factory cost and shows the cost to the consumer.

Custo de Fábrica        % do Distribuidor       % dos impostos  
Até R$ 12.000,00                5                   Isento 
Entre R$ 12.000,00              10                  15 
Acima de R$ 25.000,00           15                  20

My code:

algoritmo "Preço" 

custo_fab, perc_dist, val_dist, perc_imp, val_imp, preco: real 
inicio 
    escreva("Informe o Custo de fábrica: ") 
    leia(custo_fab) 
    se (custo_fab < 12000) entao
        perc_dist <- 5
        perc_imp <- 0 
    senao 
        se (custo_fab < 25000) entao 
            perc_dist <- 10 
            perc_imp <- 15 
        senao 
            perc_dist <- 15 
            perc_imp <- 20 
        fimse 
    fimse 
    val_dist <- custo_fab * perc_dist / 100 
    val_imp <- custo_fab * perc_imp / 100 
    preco <- custo_fab + val_dist + val_imp 
    escreval("Preço ao consumidor: ", preco)
