When the total length of the piping exceeds 70 m, calculate the amount of additional charge based on the following requirements.
Note: If the calculation produces a negative number (i.e. a "minus" charge), of if calculation results in an amount that is less than the "Additional charge
amount for 70", perform the additional charge using the amount shown in "Additional charge amount for 70 m".
