what are your thoughts about it?

anonymous · Answer

Honestly I have no clue how to do it, I've worked on it for hours but I can't understand it.

amistre64 · Answer

if youve worked on it for hours, then you must have had some thoughts that you attempted.

Well I know it isn't D because it just shows an answer and I'm looking for a problem...

amistre64 · Answer

D is wrong, but for other reasons ... 

if each box weighs a certain amount (k), 
       and we lift a certain number of them (n)


then the total weight lifted is k+k+k+...+k, the sum of k, n times is just n times k

we didint lift 112 boces, nor did they weigh the same as the other guys
