Answer 1

Liam is incorrect

He spent $3 on the comic book

Explanation:

Let

x -----> represents the amount of money he spent

we know that

The amount of money he spent plus the money he had left must be equal to the money he had when he walked into the store.

so

The linear equation that represent this problem is

x+5=8

solve for x

subtract 5 both sides

x=8-5=$3

therefore

Liam is incorrect

He spent $3 on the comic book
