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%
