The total number of pages Saul has read = 6w - 15 [ The correct option is 6w - 15 ]
Given :
- Saul reads every week.
- In his first week of reading, Saul read 50 pages.
- Each week after that, Saul read 65 pages.
- w represents the number of weeks since Saul first started reading.
To find :
The total number of pages Saul has read
- 65w + 15
- 50 + 65w
- 65w - 15
- 50 + 65 + w
Solution :
Step 1 of 2 :
Write down the given data
In his first week of reading, Saul read 50 pages.
Each week after that, Saul read 65 pages.
w represents the number of weeks since Saul first started reading.
Step 2 of 2 :
Calculate total number of pages Saul has read
The total number of weeks since Saul first started reading = w
In his first week of reading, Saul read 50 pages
Each week after that, Saul read 65 pages
∴ The total number of weeks Saul reads 65 pages per week = w - 1
∴ Total number of pages Saul has read in (w - 1) weeks
∴ The total number of pages Saul has read
= The number of pages Saul read in first week + Total number of pages Saul has read in (w - 1) weeks
= 50 + 65(w - 1)
= 50 + 65w - 65
= 6w - 15
Hence the correct option is 6w - 15
