Answer:
no. of senior citizens=x
no.of other people=7-x
cost=30=k(7-x)+(k/2)x. k is the cost of a ticket
k(7-x+x/2)
k(7-x/2)-30=0
k=60/(14-x)
now do trial and error substitution for (x<7) until u get a whole number for k also (k<30). if you have the skills you can suggest the number yourself
ie x= 2, k=5$
Rational numbers are sometimes natural numbers.
The same input is being mapped into two outputs, so this is not a function.
<h3>
Does the table represent a function?</h3>
A function is a relation that maps elements from the domain into elements from the range. Such that each element of the domain can be mapped into only one element of the range.
Here we have the table:
x y
4 2
3 3
4 5
5 6
7 7
As you can see, the input x = 4 appears two times, first it is mapped into y = 2, and then it is mapped into y = 5.
Then this table does not represent a function.

The answer would be -3. if x is -3, then in the equation x2 - x, we would replace both x with -3. So then it would be -3 times 2 minus -3 And if we multiply -3 times 2 we get -6 and -6 minus -3 is -3. I hope this helped you, sweetheart.
