没学过数学是吧？$326平均每天跌5%，持续100天，TSLA仅剩$1.93美元。。。LMAO

If 326 US dollars drops by 5% every day for 100 days, how much money will be left?

To calculate the remaining amount after exponential decay, use the formula:

 

y=a(1−r)xy equals a open paren 1 minus r close paren to the x-th power

????=????(1−????)????

 

Where: 

• 

  yy

  ????
  = the final amount
• 

  aa

  ????
  = the initial amount ($326 US dollars)
• 

  rr

  ????
  = the rate of decay (5% per day, or 0.05)
• 

  xx

  ????
  = the number of time periods (100 days) 

In this scenario: 

• 

  a=326a equals 326

  ????=326
• 

  r=0.05r equals 0.05

  ????=0.05
  (5% as a decimal)
• 

  x=100x equals 100

  ????=100
   

Plugging these values into the formula: 

y=326(1−0.05)100y equals 326 open paren 1 minus 0.05 close paren to the 100th power

????=326(1−0.05)100

 

y=326(0.95)100y equals 326 open paren 0.95 close paren to the 100th power

????=326(0.95)100

 

Calculate

(0.95)100open paren 0.95 close paren to the 100th power

(0.95)100

and then multiply by 326: 

(0.95)100≈0.00592open paren 0.95 close paren to the 100th power is approximately equal to 0.00592

(0.95)100≈0.00592

 

y=326×0.00592y equals 326 cross 0.00592

????=326×0.00592

 

y≈1.93y is approximately equal to 1.93

????≈1.93

 

Therefore, after 100 days, approximately $1.93 will be left.
