Andy started reading a 250 page book. he can read 20 pages each day. what expression represents how many pages he will have left after x days?

The expression  (250 - 20 x) represents the pages he will have left after x days.

Step-by-step explanation:

Total number of pages in the book = 250

Number of books read by Andy per day = 20

⇒Number of pages read in x days =  x ( Number of pages read per day)

                                                          = x (20)   = 20 x

So, Andy read (20 x) pages in x days.

Now, the total pages left after x days  = Total pages - Pages read in x days

                                                                 = 250 - (20 x )

Hence, the expression  (250 - 20 x) represents the pages he will have left after x days.
