Answer:

405

Step-by-step explanation:

324 seniors is 4/5 of all seniors. To find how many 5/5 of the seniors is, we find 1/5 and multiply it by 5. Since 4/5 is 4 times 1/5, divide 324 by 4. The answer is 81, which is 1/5 of the seniors. Multiply 81 by 5 to get all 5/5. 81 * 5 is 405

First move the constant to the right and change its sign to the opposite,
3m=1-4

Then calculate,
3m=-3

Then divide both sides of the equation by 3,
m=-1

So the answer is m=-1
