Question

James spent $20.16 on comic books. Each comic book cost $0.72. After he read the comic books, James sold each one for $0.20 less than he paid for it.

What is the total amount of money that James received from selling his comic books?

Answer 1

To find the total amount James received from selling his comic books, we first need to determine how many comic books he bought with the total amount he spent, which is $20.16.

Given that each comic book costs $0.72, we can calculate the number of comic books purchased as follows:

\[
\text{Number of comic books} = \frac{\text{Total amount spent}}{\text{Cost per comic book}} = \frac{20.16}{0.72}
\]

Calculating that:

\[
\frac{20.16}{0.72} = 28
\]

So, James bought 28 comic books.

Next, we need to determine the selling price of each comic book. He sold each comic book for $0.20 less than what he paid. The selling price per comic book is calculated as follows:

\[
\text{Selling price per comic book} = \text{Cost per comic book} - 0.20 = 0.72 - 0.20 = 0.52
\]

Now, we calculate the total amount of money James received from selling all of his comic books:

\[
\text{Total amount received from sales} = \text{Number of comic books} \times \text{Selling price per comic book} = 28 \times 0.52
\]

Calculating that gives us:

\[
28 \times 0.52 = 14.56
\]

Therefore, the total amount of money that James received from selling his comic books is

\[
\boxed{14.56}
\]
