Formatter crashing on valid prices

Time: 0:00

What it should do

format_price(amount) should return the amount formatted as a price string, e.g. format_price(5) -> "$5".

What goes wrong

Calling format_price(5) crashes with: TypeError: can only concatenate str (not "int") to str.

Hints

This is a type errors bug

Totals that concatenate, sorts that put 10 before 9, comparisons that refuse to run.
