Let the cost of one book= x cents
Let the money john have= y cents
According to the question,
45x=y ...eq(1)
(45+5)(x-5)=y
50(x-5)=y
50x-250=y ...eq(2)
On subtracting (1) from (2).
(50x-250)-45x=y-y
5x-250=0
x=250/5
x=50
Thus, cost of each book is 50 cents and john has 2250 cents.
Hope it helps.
Don't feel shy in saying thx if it helps.

Hola
Step-by-step explanation:
Well if this is based off the first thing I answered, then 1. C
as I told you before, every time the x axis values go up one, the y values go up by x2 (aka times 2). Therefore it’s C.
2. It is linear because the unit change (amount it goes up aka slope) is the same since it’s alway x2. Hence the line on a graph would look linear
The two fours are recurring
Quotients can sometimes be irrational so it is necessary to estimate them, products on the other hand are only rational, provided they aren't multiplied by an irrational, so it is not necessary to estimate
