From what I understood in the problem, the total budget that covers all types of media is only $1,000 per month. For the allocation, each type of media would get at least 25% of the budget. If we infer on this information, there should only be 4 types of media, at least. This is because four 25% portions would equal to 100%. If it exceeds 25% for each of the four types, it would be over the $1000 budget. With that being said, it is also possible that there will be 3 or 2 types of media. Nevertheless, let's just stick to the least assumption of 25% for each of the 4 types.
If local newspaper advertising is one of the four types, then:
$1000(25%) = $250
It would get $250 from the overall budget.
