Question

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. how many pages long was sonia's paper?

Answer 1

For edmentum

the answer is 34

three pages cost $13 in remain Pages cost $3 each, for a total of $106. in = the number of pages typed and in -3 = the number typed at $3. here is the equation:

13+3(n-3) =106
13+3n-9=106
3n+4=106
3n=102
n=34

Answer 2

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. Here's our equation:

`13+3(n-3)=103`

`13+3n-9=103`

`3n+4=103`

`3n=33`
