print (int(cost))

Answer 1

Atena Molaie as Lisa said, int() does not round up. The function to round up is round()
Use that

Edit: round() does simply that, it rounds up or down, whichever is correct

Answer 2

The task description asks you to round ***up***.
int() just cuts of the decimals but does not round up

Answer 3

ceil() from math module can round up

Answer 4

Brain & Bones it occurs when somehow the test cases are conveniently in the validity range of code, this indicates that the test cases aren't built with extreme/boundary cases in mind.
