I answer C with the following logic: The 10 page that was revised twice, was revised once earlier as part of the 40 pages that was revised the first time. Hence, (100*$5) + (40*$3) + (10*$3) = $650 Well, perhaps I think too much.

(D) $680 (E)$770

For 100-40-10=50 pages only cost is 5$per page for the first time page is typed - 50*5=250$;
For 40 pages the cost is: first time 5$+ 3$ of the first revision - 40*(5+3)=320$; For 10 pages the cost is: first time 5$ + 3$of the first revision + 3$ of the second revision - 10(5+3+3)=110$; Total: 250+320+110=680$.

OR:
100*5+40*3+10(3+3)=500+120+60=680.

Hope it's clear.
