D. 500-3.5X (MISTAKE)

OpenStudy (anonymous):

500 B = X M = 2B => M = 2X P = M/2 => P = 2X/2 = X ....ADDING ALL 500 - X - 2X - X 500 - 4X

ok nevermind the answer is C because m=2b p=1/2m therefore b+p=m

OpenStudy (anonymous):

There are 500 pieces of paper. Bob uses X amount and therefore at that point the amount remaining would be 500 minus that X amount or 500-X. If Mike uses twice as much as Bob then he is using 2X and therefore there is 500 - X - 2X. Pete then uses half of the amount that Mike used, which was 2X, meaning he used X. Leaving 500 - X - 2X -X. When when combine like terms we get 500 - 4X.
