Assume that John Travoltage and the carpet are neutral to start. After he rubbed his foot on the carpet on took negatives, what charge is on the carpet and why

Same charge, positive.

Please see below as the answer is self-explanatory.

Explanation:

Due to the principle of conservation of the charge, if both the man and the carpet were neutral to start, any negative charge transferred to the man by the carpet, must have its positive counterpart on the carpet, so the system man + carpet can keep neutral as required by this principle, due charge can't neither created nor destroyed.
