Let the width be x
The length would be 2x-5
So, 2(x+2x-5)=80
3x-5=40
3x=45
x=15.
So the width is 15 and the length would be 25.
Using the Fundamental Counting Theorem, it is found that there is a probability of getting the correct Social Security number of the person who was given the receipt.
<h3>What is the Fundamental Counting Theorem?</h3>
It is a theorem that states that if there are n things, each with ways to be done, each thing independent of the other, the number of ways they can be done is:
In this problem, there are 5 digits, each with 10 possible options, hence the number of options is given by:
Only one option is correct, hence the probability is given by:

Answer:
The price paid is $96
Step-by-step explanation:
Here, we want to calculate the price paid on a $120 bookshelf after applying discount
Firstly we calculate the amount of discount applied
That will be;
20% of 120
= 20/100 * 120
= 24
So the amount paid is;
120 - 24 = $96
