Syntax errors would prevent a program running at all, while runtime errors would prevent the program from running properly
The subtotal variable is to take a numerical value (i.e. integer or float).
From the question, the first line gets a string value for the subtotal variable.
So, the first error in the program is:
subtotal = input("Enter total before tax:")
The second error is in printing the output on line 3.
The line 3 is an error because the line attempts to print a numerical value and a string value without converting the numerical value to string value.
So, the correct program is:
subtotal = float(input("Enter total before tax:"))
tax = .08 * subtotal
print("tax on " + str(subtotal) + " is: " + str(tax))
