Oops, try again. get_average(alice) raised the following error: 'float' object is not iterable

I feel I'm messing up the last line. And I don't know why I'm getting float object not iterable message

```
# Add your function below!
def average(numbers):
total = sum(numbers)
total = float(total)
return total/len(numbers)
def get_average(student):
homework = average(student["homework"])
quizzes = average(student["quizzes"])
tests = average(student["tests"])
return sum(homework*0.1 + quizzes*0.3 + tests*0.6)
```
