An enterprise uses two subscription models for its cloud service. Model A: a fixed monthly fee of N30 and a charge of N0.05 per transaction. Model B: a fixed monthly fee of N20. For each month, the first 150 transactions are charged at N0.07 each and any transaction beyond 150 is charged at N0.04 each.
