Question

Sharita does special typing jobs for scientists. she charges $7 for the first 3 pages and $3 for each additional page of scientific typing. sonia, a biologist, paid $100 to have a research paper typed. how many pages long was sonia's paper?

Answer 1

Sonia's research paper was 34 pages long.

Step-by-step explanation:

To determine the number of pages in Sonia's research paper, we can set up an equation using the given information. Let's denote the number of additional pages as x. We know that the total cost to Sonia is $100.

According to the pricing scheme, the first 3 pages cost $7, and each additional page costs $3. So, the equation becomes:

7 + 3x = 100

To solve this equation, we isolate the variable x by subtracting 7 from both sides:

3x = 93

Finally, divide both sides by 3 to solve for x:

x = 31

Therefore, Sonia's research paper is 31 additional pages long, making the total number of pages 31 + 3 = 34 pages.

Answer 2

100 divided by 3 = 33 now 33 - 7 =26.
so she wrote 26 pages.
