RFISupportingMarketingBurnBP._transferHook(address,uint256) (#965-978) performs a multiplication on the result of a division:
-tTotalTakeAmount = amount.mul(totalFeesToTake).div(100) (#968)
-tTotalTakeAmountMarketing = tTotalTakeAmount.mul(marketingFee).div(totalFeesToTake) (#969)
Consider ordering multiplication before division.
