Answer:
C
Step-by-step explanation:

6!+7!+8!=(n)(6!)
calculate the individual values first:
6!=720
7!=5040
8!=40320
plug them into the equation:
720+5040+40320=n720
solve for n
5760+40320=n720
46080=n720
divide both sides by 720 to isolate n
46080/720=n720/720
64=n
I am pretty sure the correct answer is $146.75. Hope this helps!!!!!!!
