I don’t understand where test 16 is failing. The test name is very vague, and with the test data in the story it prints what’s expected (actually, the story sample code and sample output don’t match up).
I checked the browser console and I’m only seeing test failures relating to the spend chart.

Did you compare your output to the output in the example?
Your output:
*************Food*************
deposit 1000.0
groceries -10.15
restaurant and more foo -15.89
Transfer to Clothing -50.0
Total: 923.96
Does something look wrong with the number values?

you should see also this in the console
AssertionError: '****[47 chars] 900.0\nmilk, cereal, eggs, bac -45.67\nT[40 chars]4.33'
!= '****[47 chars] 900.00\nmilk, cereal, eggs, bac -45.67\nT[40 chars]4.33'
the first line is your code, the second line is the expected
Thanks, now I see how mine is different.
BTW, the ‘example usage’ and ‘example output’ in the instructions don’t match up. (One says ‘deposit’, the other says ‘initial deposit’.)
