Why is final_price = price *1.07 different from final_price = price *107/100
Was doing the ballpark orders problem using python. My code worked in first two cases, but hidden cases failed. A Google search found this as a possible fix and sure enough it now passed. It must be a rounding issue?

Yep. Rounding error.
Even though BODMAS/PEMDAS says it shouldn't matter, it does. Seems that division causes rounding issues when performed anywhere except last.
I think I had to add the tax to the total separately to pass test case #5.
