Answer:
- 3 days = 75.36%
- 1 week = 51.68%
Step-by-step explanation:
You can use the future value formula to calculate this:
Future value = Amount * (1 + rate)^ no. of periods
As there is no given amount, simply calculate using (1 + rate)^ no. of periods.
After 3 days:
= (1 + (-9%))³
= 0.753571
= 75.36%
After a week:
Week = 7 days
= ( 1 + (-9%))⁷
= 0.51676
= 51.68%
