sacha 7410 Report post Posted June 21, 2020 My donation is $120 for the half hour. If I offer a 10% discount every minute what is your final donation after 30 minutes? If you got this far, well done. But I want more. The parameters are still the same, $4 per minute, 10 % off every minute but what is your donation after 113 hours? Show me your perfect equation.
