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

Answer:The equation is provided below:

$7 = amount for the first 3 pages

$3 = amount for additional pages

$97 = total amount that has been paid for the typing job

We have to deduct the amount of $7 to know how much is the remaining amount to consider or that has been used for the remaining pages.

$97 - $7 = $90

Then, we have to divide the amount of $90 to the amount for the additional pages.

$90 / $3 = 30 pages

Then, add the first 3 pages for $7 to the answer.

30 pages + 3 pages = 33 pages.

The total pages that has been typed by Sharita was 33 pages.
