LeBron is planning for his wedding with his fianc Amira. They believe they need RM30,000 for the ceremony to be held exactly three years from today. Amira is planning to start depositing RM300 per month for the event beginning next month in a unit trust that would provide her 5% return per year on average. If LeBron were to invest in another unit trust investment that will provide him 7% return per annum, how much should he invest every month beginning today to ensure that their savings will be enough in three years time?
