50. If a Class C amateur applies for renewal of his license for another 3 years but is 14 months expired and the prescribed license fee is P144.00 per year, how much shall he pay NTC for his Radio Station License renewal excluding filing fee?

Explanation

The Class C amateur's license is expired by 14 months, which means he needs to pay for the renewal of those 14 months in addition to the next 3 years.
