Remember that the general decay equation is:

where 

 is the amount after a time 


 is the initial amount 

 is the the decay percent in decimal form
The first ting we are going to do is find 

 by dividing our <span>decay rate of 25% by 100%: </span>

.
We also know from our problem that 

. Lets replace 

 and 

 in our formula:


We know now that our decay rate is 0.75, and since 0.75<1, we can conclude that 
this situation represents exponential decay.
Now, to find the initial amount, we are going to solve our equation for 

:


Notice that 

 will depend on the number of ours
