Answer:
I hope you meant to put ( 4 less than the quantity of 8 times n) because otherwise your question would be incomplete. ( 8 times what) would be the question asked so I hope I helped but I am very sorry if I am wrong and you actually meant to put 4 less than the quantity of 8 times!
Explanation:
4 - (8)n or 4 - 8n or -8n + 4
( It can be either 3 of these)
