The price of one senior citizen ticket is 8$ and one student ticket is 12$.
<h3>What is the equation?</h3>
The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
Let the price of one senior citizen ticket = x
And the price of one student ticket = y
Given that, on the first day of ticket sales, the school sold 13 senior citizen tickets and 13 student tickets for a total of $260
The school took in $212 on the second day by selling 13 senior citizen tickets and 9 student tickets.
13x +13y = 260
13x + 9y = 212
Subtract the equation from first
13x +13y - (13x + 9y) = 260 - 212
4y = 48
y = 48/4
y = 12
Substitute the value of y in the equation 13x + 9y = 212
13x + 9(12) = 212
13x + 108 = 212
13x = 212 - 108
13x = 104
x = 104/13
x = 8
Hence, the price of one senior citizen ticket is 8$ and one student ticket is 12$.

The number of ways when the choice is not relevant is 1716
<h3>How to determine the number of ways?</h3>
The number of letters are:
Letter, n = 13
The letter to choose are:
r = 6
<u>Relevant choice</u>
When the choice is relevant, we have:

This gives

Evaluate
Ways = 241235520
Hence, the number of ways when the choice is relevant is 1235520
<u>Not relevant choice</u>
When the choice is not relevant, we have:

This gives

Evaluate
Ways = 1716
Hence, the number of ways when the choice is not relevant is 1716
