B. The domain would only include positive numbers.

C. The domain would only include positive integers.

D. The domain would include all real numbers.

Answer 1

Let

f(x)--------> the cost per person to attend the school dance

x---------> the number of persons

we know that

The domain would only include positive integers, because the number of persons can not be negative or fractional number

The range of the function would only include positive numbers, because the cost can not be negative

therefore

the answer is the option C

The domain would only include positive integers.

only include positive numbers
