The base biennial licensing fee for a commercial drone fleet management system is £540.00. Subscribers pay this base fee in 18 equal instalments.
A corporate customer receives a discount of 3% off this base biennial fee for every active drone safety certification they hold.
Construct a general mathematical expression to calculate the cost (in pounds) of each instalment.
Use the variable c c\,c to represent the number of active safety certifications.
