Freight Table Calculation

I have the following freight table

Ihavethefollowingneighborhoodtable

Where in the table, select > idSaida = 1 = Center and idDestino = 2 = Abranches In this case a product will be collected at the Center and delivered to Abranches. This service was made by moto - dotMoto If we add up the result will be 2 points.

The problem is that I am not able to develop the calculation of this score. Has anyone here developed something similar? Do you have any idea?

Producing a test, the first result of print_r ($ data):

[0] => Array
    (
        [tiposervico] => 0
        [endereco] => asdfasdf
        [numero] => 
        [bairro] => 1
        [cidade] => Curitiba
        [falarcom] => 
        [idChamada] => 34
    )

[1] => Array
    (
        [tiposervico] => 1
        [endereco] => afsdf adf asf
        [numero] => 
        [bairro] => 2
        [cidade] => Curitiba
        [falarcom] => 
        [idChamada] => 34
    )

I tried to do this as I entered the services ...

public function addChamadaServico($dados)
{


    $campo['idSaida'] = $dados[0]['bairro'];
    $campo['idDestino'] = $dados[1]['bairro'];

    $sql = "SELECT * FROM tabelafrete WHERE idSaida = ".$campo['idSaida']." AND idDestino = ".$campo['idDestino']."";
    $consulta = $this->db->query($sql)->result();

    //echo $sql;

    foreach($consulta as $valor){
        $contagem = $valor->pontoMoto * 15;
        echo $contagem; 
    }

}

So far, apparently it works ... but the fact is that you can have multiple "destinations" in different neighborhoods and a return, or multiple returns in different neighborhoods ... does anyone have any ideas?
