Answer:
The correct answer is 720.
Step-by-step explanation:
There are 10 different styles of toilet paper available in the house.
We need to choose 3 types from these 10 styles.
Therefore number of ways we can select these 3 types are given by ![\left[\begin{array}{ccc}10\\3\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D10%5C%5C3%5Cend%7Barray%7D%5Cright%5D)
ways = 120 possible ways.
Now we need to put these toilet paper in each of the 3 bathrooms. So we have possible 3! = 6 possible ways.
Therefore the number of ways one would select 3 toilet paper and then placing each of the bathrooms in the house is given by 120 × 6 possible ways = 720 ways.
This could be interpreted 2 ways

Answer: 35 adult tickets and 15 student tickets were sold.
Step-by-step explanation:
Let x represent the number of adult tickets that were sold.
Let y represent the number of student tickets that were sold.
20 more adult tickets were sold and student tickets. It means that
x = y + 20
Adult tickets for the school play cost 6 dollars and student tickets cost 4 dollars. If $270 was collected, it means that
6x + 4y = 270- - - - - - - - - - - 1
Substituting x = y + 20 into equation 1, it becomes
6(y + 20) + 4y = 270
6y + 120 + 4y = 270
6y + 4y = 270 - 120
10y = 150
y = 150/10
y = 15
x = y + 20 = 15 + 20
x = 35
