what do you think

anonymous · Answer

I think it is either D or B. The extra x isn't suppose to be there lol.

anonymous · Answer

is c suppose to be 190?

anonymous · Answer

No

anonymous · Answer

ok why do you think it is D or B

anonymous · Answer

Well I think B is most likely the answer.

anonymous · Answer

that is close but that answer would be A
because the 6 letter words + the 7 letter words will =190
and the letter of 6 letter words and  7 letter words  will =30
