Found this on a practice test, seems easy but I still can't understand where I'm wrong

If a certain manuscript has 100 pages, of which 40 were revised only once, 10 were revised twice, and the rest required no revision, what was the total cost of having the manuscript typed
a) 430
b) 620
c) 650
d) 680
e) 770
Answer is D

My answer choice was 650, but I was marked wrong for it.
100*5=500 (for the 100 pages typed for the first time)
40*3=120 (for the first round of revisions)
10*3=30 (for the ten pages revised twice)
500+120+30=650, Where am I wrong? Am I just missing something here?[/spoiler]
