Tell us what’s happening: While all other tests pass, test #6 fails with a rounding error that returns 50.35 instead of 50.36. I could only satisfy this test with a fudge… if round(cost,2) == 50.35 : cost += 0.01 Copilot tells me there is no sane solution to satisfy all tests by producing the expe…

It works with (acc.toFixed(2) * subscription).toFixed(2) All tests

Apparantly taking ths sum of the basic costs first and then multiplying with the discount, and taking the sum of each of the basic costs multiplying with the discount (the way the solution applies), produce different results after rounding.

While in normal Python environment it’s permissable to use bulit-in functions or methods as keys of dictiona…
