Some problems on the GMAT Quant section cannot be solved with formulas or with algebra. For some problems, the GMAT makes you wrestle with the number properties themselves. For a discussion of difficult numerical reasoning questions, as well as the full solution to this question, see:

Re: Peter went to the store to buy paint. Small cans cost $30 [#permalink] ### Show Tags 23 Dec 2013, 14:45 Not really a 700 question but nevertheless an interesting one: Choice A: If you buy one can at 80, than there are no way to reach the$220. If you buy zero also. And if you buy three than you are already at 240. Than you need two cans at $80 and two at$30. CORRECT

Choice B: no clear information

Hope it helps!

Not really a 700 question.
Not really a Number Property question, this should be tagged as a Word Problem

Integer constraints are commonly tested on the GMAT

This problem is meant to deal with exactly that

I suggest always simplifying first

3x + 8y = 22

And then x = 22 - 8y / 3

Only 2 works here

Cheers!

J Dear jlgdr, By your statement "Only 2 works here", do you mean statement #2? In other words, do you mean to imply that (B) is the answer? If not, it's not clear to me what you think the answer is. Furthermore, I would argue that introducing algebra into this problem doesn't necessarily facilitate the solution, and for some students, may confuse them.
