Trip often, scattering remaining income (3,6)
I believe the answer is:
net profit
'remaining income' is the definition.
'net profit' can be an answer for 'income' (net profit is a kind of income). I'm unsure of the 'remaining' bit.
'trip often scattering' is the wordplay.
'scattering' indicates an anagram.
'trip'+'often'='tripoften'
'tripoften' with letters rearranged gives 'NET PROFIT'.
Can you help me to learn more?
(Other definitions for net profit that I've seen before include "What's finally made" , "Excess of sales over costs for potent fir" , "Actual money to be made" , "return from business" , "Earnings after all deductions" .)
