000. He is left with 75,Lets say instead he donates 10,000.That leaves 90,000.......
Craig inherited d dollars. he has two options. Option 1: pay 1/4 of the inheritance in taxes. Option 2: donate w dollars of his inheritance to charity and pay 1/4 of the remaining amount in taxes. How many dollars less will he keep if he chooses option 2 instead of option 1?

(a) 1/4w
(b) 1/4d
(c) 1/4(d-w)
(d) 1/4(w-d)
(e) 3/4w

OK

The answer is E.

Example; He inherits 100,000. 1/4 of that is 25,000. He is left with 75,000
Let's say instead he donates 10,000. That leaves 90,000. 1/4 of 90,000 is 22,500. He is left with 67,500. The difference is -7,500. That is 3/4 of the 10,000 he donated.

d - 1/4d = 3/4d

(d -w) - 1/4(d-w) = 3/4 (d-w) = 3/4d - 3/4w.

The difference between the two is 3/4w.

Hope that helps.

If he just pays the taxes the answer is d - 1/4 d = 3/4 d

If he gives some to charity first then what he has left is d - w - 1/4(d - w) = 3/4d - 3/4w

The difference is 3/4d - (3/4d - 3/4 w) = 3/4 w

-
(c) 1/4(d-w) just a guess

The answer is A
