Percentage of pages of a book read by Katie = 32%
Total number of pages of the book read by Katie = 80
Let us assume the number of pages that the book has = x
Then
(32/100) * x = 80
32x = 80 * 100
32x = 8000
x = 8000/32
= 250
So the book has a total of 250 pages in it.
Then
The number of pages that Katie still needs to read = 250 - 80
= 170
So Katie needs to read 170 more pages in the book.
Answer: 400 because 40 multiplied by ten equals 400 hundred, so basically it's just 40 multiplied by 10.
The answer is line A. Because 1 is the Y - Inrercept in the equation and Line A fits that. and it goes up 2 over 1 which is the slope in the equation
Factoring may be the easiest one
