Mrs. hilt read 21 books. each book had exactly 2,010 words in it. she sold five of her books for $4.95 each. how many words did mrs. hilt read?

The fact that she sold 5 of her books has no affect on the answer because she has already read the books. You just have to do the 21 books times the 2,010 words per book. This gives you 42,210 words. Hope this helps.
