Actually, the problem itself is elementary, but the interpretation of the equation has presented a significant cause for argument. I was originally adament about what I saw as a simple math problem, even applying the distributive property to what appeared to be the complete denominator. It wasn't until I was convinced that everything to the right of the division sign was NOT necessarily the denominator that I saw that 288 could be considered the obvious answer, just as I had seen 2 to be.
In the future, I will "parenthesize" in a manner that makes it obvious as to which order is to be followed.
