Can it buy 40 desks? No.
The budget is $500 but to buy 40 desks would require $6000.

I think the answer you're looking for is that answer A alone is sufficient to determine the answer. B doesn't help. If the budget is less than $6000 then we don't need any additional info to know that they can't buy 40 desks.
