Below are the errors.

(34) error C2447: '{' : missing function header (old-style formal l
ist?)
(91) error C2447: '{' : missing function header (old-style formal l
ist?)

You are missing a '{' between these lines.

double taxAmount(double taxRate, int perExempt, int numberofPeople, double taxRate)

	double taxRate;

>>You are missing a '{' between these lines.
He is actually misplacing '{'.
The defination of function in C++ is :

<return_type>     <function_name>([parameteres])
{
    //codes
}

rather than

{
<return_type>     <function_name>([parameteres])

    //codes
}

So make your definition as:

double taxAmount(double taxRate, int perExempt, int numberofPeople, double taxRate)
{
    //codes
}
