I am completely stumped with how to start this formula. It is in reference to billing false alarms occurring in a month. The first 1 is $50, a 2nd is $100, after 3, it jumps to $200 each.
If there were 5 false alarms in the month, the total would be $750 (1@$50, 1@$100, 3@$200).
Any help would be appreciated.
