I'd be willing to bet that you read that as 25 "times" 41.

The students were given four choices as a correct answer:

B) (20 X 40) + (40 X 1)

C) (25 X 40) + ( 25 X 1)

D) ( 25 X 40) + (26 X 1)

Now, before you put on your number crunching hat, consider the rereading the "times" sign in the original problem. If you read the X as "groups of", you become aware that we are looking for some combination that is equivalent to 25 groups of 41 or 41 groups of 25.

Do you see a choice that makes 41 groups of 25? I do! Decompose the 41 into 40 and 1. Does that help? The answer is C, and I'll C U L8TR.
