# Couple of math questions

I have a couple math questions that I am a bit rusty with. I know they are probably really easy, but bare with me, as I haven't done problems like these in a while.

Here we go:

A man makes $75,000. He must pay federal personal income tax of 10% on the first$12,000 of his income, 15% on the next $38,000, and 27% on the income up to$100,000.

My question is: do I take the 27% out of what is left after I subtract the $12,000 and$38,000 or no?

My answer was $13,650... Is that correct? The average annual salary of person A is$62,000, while the average salary of person B is $48,000. What percent more does person A make than person B? I did this one, but I don't think it's correct. I just really forget how to do problems like this. My answer was 12.73% or somewhere in that range. Any help is appreciated!!!!! 2.

Be careful not to subtract the 12,000 from this because it has no bearing on how much the person makes aboove 38,000. Question 2:When you talk about by what percent x is more than y, you mean what percent of y would you have to add to y to get x. So 3 is 50% more than 2 because 2 + (.5*2) = 3. In other words find the difference between x and y and see what percent of y this is. 3 - 2 = 1, 1 is 50% of 2, so 3 is 50% more than 2. 3.

The second one, I can't remember how to do such a thing, so I will not say anything

edit... Leonhard that was how I remember this sort of problem in Economics. However, the problem states "15% on the next $38,000" In my thinking I said that meant up to an income of$50,000.

You would have a table

0 - 12000 at 10%
12000 - 50000 at 15%
50000 - 100000 at 27%

Which would give

1200
5700
6750 (because 75000 - 50000 = 25000 and that at 27% is 6750)
_____
total of 13650
