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.

I think its D...because of the word "ONLY" - it says 40 pages were revised ONLY ONCE.....

(A) \$430
(B) \$620
(C) \$650
(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.
