Answer:
1,000,000,000 identification numbers are possible.
Step-by-step explanation:
We are assigned a 9 digit identification number.
Each digit is a number from 0 to 9. So, each digit has 10 different choices.
Using the Fundamental Counting Principle (is better than the tree diagram) because it's simpler. To illustrate this, we can attempt to draw a tree diagram.
The first column will be the digits 0 to 9.
Then for each of those digits, we need another 0 to 9.
As you can imagine, the amount of numbers grow exponentially, so using the Fundamental Counting Principle is simpler.
And since we have a 9 digit identification number, with each digit having 10 choices, the total number of identification numbers possible are:
So, 1,000,000,000 identification numbers are possible.

Answer:
Step-by-step explanation:
Let the price of 3-pack of Spinners be s and a dozen of Fly-Boys be f.
<u>Given:</u>
<u>Solve the equation for f:</u>
- s = 1/3f
- f = 3s
- f = 3*$3 = $9
