Question

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.

Answer 1

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.
