Constraints

All values in input are integers.

1 \leq A, B, T \leq 20

Input

10

Five biscuits will be produced three seconds after activation.

Another five biscuits will be produced six seconds after activation.

Thus, a total of ten biscuits will be produced within 7.5 seconds after activation.
