_____

There are all kinds of ways this might make sense, but none of them are supported by the information given in the problem statement.

Answer 2

No, the solution (6.5,$ 95.25) do not make a sense.

Since, the number of people going for a movie can't be in decimals.

Explanation:

The function h(x) represents the amount of money spent where x is the number of friends at the movies.

The domain of such a function has to be whole numbers.

Because the number of people that go for a movie must exist as a whole they can't exist in decimals.

( i.e. either no one will go.

1 will go.

2 friends will go and so on)

i.e. the domain is the set of all non-negative integers.
