Question 679401
Let's break this word problem down into pieces. 

First, Taylor read 4 times as many pages as Aniya.
Aniya = x 
Taylor = 4x
[The amount Aniya has read is set to default x. Since Taylor read 4 times as many, the expression given to her is 4x.]

Second, Taylor read 100 pages. If Taylor has the expression 4x, then we can create an equation with her expression equaling to 100.
4x = 100

Next, we must solve for what x is equal to.
4x = 100
(Divide 4 on both sides of the equation.)
 x = 25

Since we now know that x is equal to 25, we can conclude that Aniya read a total of 25 pages. Finally, we must subratract Aniya's amount from Taniya's amount to get a difference of: 75 pages
100 - 25 = 75

Answer: Taylor read 75 more pages than Aniya.
