Answer 1

Roberto Pereira

Your code seems to be making incorrect comparisons when finding `expensive` value, since the values in `prices` list are still strings, not numbers. If you want to find the most expensive value (largest number), need to convert to numbers first. Add this after first line:

prices = [float(x) for x in prices]

Now you can also remove the `float()` conversion in the other lines, since the values are now numbers.

Strangely enough, only 1 of the 7 tests captures this sneaky logical error. Hope this was helpful.
