Question

sadie has already written 1 page, and she expects to write 3 pages for every additional hour spent writing. How many hours will sadie have to spend writing this week in order to have written a total of 49 pages

Answer 1

Let's call x to the number of hours

She writes 3 pages per hour, then after x hours she writes 3x pages

She already wrote 1 page and wants to write a total of 49, so she has to write 49 - 1 = 48 pages.

Then, the equation is:

3x = 48

x = 48/3

x = 16 hours
