Answer:
No, (12.5, $139.5) is not a possible solution to the given because the input is not feasible
Step-by-step explanation:
We are given that g(x) represents the function used to calculate the amount to be paid where x is the number of friends
This means that:
The input of the function:
It is the number of friends
Since we cannot have a fraction of a person nor a negative value of a person, therefore, the input must be a positive integer
The output of the function:
It is the amount to be paid
Since we cannot have a negative value for the amount to be paid, therefore, the output must be a positive real number (can be a positive fraction or a positive whole number)
Now, for the given:
(12.5, $139.5)
The input is 12.5 which means that we have 12.5 friends. This is not feasible
Therefore, the given order pair is not a possible solution to the function
Hope this helps :)
