Sharita does a special typing job for scientist she charges 7 dollars for the first 3 and 3 dollars for each additonal page of scientist typing, sonia, a biologist, paid 100 dollars to have a research paper typed how many pages long was sonias paper

Let's just work through this one using logic. Here's what we know: * it costs $7 for first 3 pages * it costs $3 for each additional page * $100 total was spent$100 - $7 leaves us with $93 remaining. Divide that $93 by $3 to get 31 pages. Add that 31 pages to the initial 3 you spent $7 on and get a total of 34 pages for $100.
