Question

Margaret is reading a book. The number of pages she has left to read is 276−35d276−35d , where d represents the number of days she has been reading. What does each part of the expression represent?
35= ___
276=____
35 D=____

(options for answers: The number of pages read during one day, the total number of pages in the book, the number of pages she has read during D days, the number of pages she has read during 1 week)

I believe these are the answers but, I am not sure!

35= The number of pages read during 1 day
276= the total number of pages in the book
35D= the number of pages she has read during D days, the number of pages she has read during 1 week

Please help! ^^^^^^

Answer 1

276 - 35d

276 = total pages
35 = pages read per day
35D = number of pages she has read during D days

Answer 2

Let

P-------> the number of pages Margaret has left to read

d-------> the number of days Margaret has been reading

we know that

$P=276-35d$

This is a linear equation

where

$-35$ ------> is the slope of the equation

represent $35\frac{pages\ read}{day}$

$276$ ------> the total number of pages in the book

$35d$ ------> the number of pages she has read during d days
