Lucy earns 52 dollars each week working part-time at a bookstore. She earns one additional dollar for each book that she sells. Let 'A' be the amount (in dollars) that Lucy earns in a week if she sells 'B' books.

Write an equation relating A to B . Then use this equation to find the amount of money Lucy earns if she sells 15 books.

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.

the answer is 13/48
