17-(8 to the power of 3-45) times 7 times 2 -1324=-7845
Answer: 32760 ways.
Step-by-step explanation:
To solve this, we first determine the number of ways to select 4 countries from 15, we calculate number of ways to visit these 4 places then we multiply.
Selecting number of ways to choose 4 cities from 15 is by using the combination formula, which becomes 15C4
Number of ways to visit these 4 cities = 4!
Hence,total number of ways of visiting these 4 cities = 15C4 * 4! = 32760ways
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:
