Came to bust? (8)
I believe the answer is:
totalled
'came to' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for totalled that I've seen before include "came to" , "Determined the sum of" , "Summed" , "completely destroyed" , "Added together" .)
