The tip percentage of a trip

The report's core needs one small, pure calculation: the tip as a percentage of the fare. TLC data includes zero and negative fares (refunds and adjustments), which must not produce a percentage.

Functiontip_percentage(trip); trip has fare_amount and tip_amount

Returnstip_amount / fare_amount * 100 rounded to 1 decimal place; None when the fare is 0 or less

Rulethe trip is not changed
