Answer:

Kapow Comics is the best deal per comic book.

Step-by-step explanation:

Given:

At Comic world 4 books =$6

At Kapow Comics 7 books = $8.75

We need to find the best deal per comic book.

Solution:

First we will find the rate of 1 comic book at Comic World.

Now we know that;

4 books = $6

1 book = Cost of 1 comic book.

By using Unitary method we get;

Cost of 1 comic book = [tex]\frac{6}{4}=\$1.5[/tex]

Hence Cost of 1 comic at Comic World is $1.5.

First we will find the rate of 1 comic book at Kapow Comics.

Now we know that;

7 books = $8.75

1 book = Cost of 1 comic book.

By using Unitary method we get;

Cost of 1 comic book = [tex]\frac{8.75}{7}=\$1.25[/tex]

Hence Cost of 1 comic at Kapow Comics is $1.25.

Now comparing both side we can say that;

Cost of 1 book is Less at Kapow comics than at Comic World.

Hence Kapow Comics is the best deal per comic book.
