4. Adrian and Rory started comic book collections at the same time. Adrian

started with 12 comic books and buys 4 more each month. Rory started with

8 comic books and buys 4 more each month. Will they ever have the same

number of comic books? If so, after how many months? Use an equation to

justify your answer.

As both are adding same number of comic books each months, they will not have same number of books. Adrian will have 4 more comic books.

Step-by-step explanation:

Given,

Adrian starts with 12 comic books and add 4 each month.

Let,

m be the number of books.

A (m) = 4m+12

Rory starts with 8 comic books and add 4 comic books each month.

R (m) = 4m+8

As both are adding same number of comic books each months, they will not have same number of books. Adrian will have 4 more comic books.
