The exponential function that models this situation is:

------------------------------------------
A decaying exponential function has the following format:

In which:
- y(0) is the initial value.
- r is the decay rate, as a decimal.
In this problem:
- The stock started at $225, thus
. - Declines at a rate of 25% every 2 weeks, thus

The equation is:

Answer:
12
Step-by-step explanation:
(2x-8+2x+10)/2 = 25

4x+2 = 50
4x = 50-2
4x = 48
x = 48/4
x = 12
