sharita does special typing jobs for scientists. she charges 13$ for the first 3 pages and 3$ for each additional page of scientific typing. Sonia , a biologist , paid 103 to have a research paper typed ?
33 pages because you subtract 13 from 103 which is 90 then divide that by 3 and that gives you 30 pages then you add the other 3 pages that costed $13.
