Your answer is C) 5.
First multiply each answer choice by how much borrowing a book costs for each Club. Add the values to each monthly fee and see if they are the same.
How I solved:
ABC Book Club
$2 per book x 5 = $10
$40 (monthly fee) + $10 = $50
Easy Book Club
$3 per book x 5 = $15
$35 (monthly fee) + $15 = $50
As you can see, they equal the same value.
I hope this helped you.
