Katie and becca each bought a new book for $50 . Katie sold her book to the bookstore for 25% less than the original price. . Becca sold her book to the used bookstore for 40% less than the original price Enter how much more money in dollars Katie received for her book than becca received for her book

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
