Answer:

$12 + 4b < 7.50b$

Step-by-step explanation:

Given

Reader' Book Club

$Membership = \$12$

$Book = \$4.00$ per book

Perfect Page

$Book = \$7.50$ per book

Required

Write an inequality to represent the situation

$7.50b$

For Reader's club to be less than Perfect Page, we have:

$12 + 4b < 7.50b$
