Answer
So, the rental cost for each movie is \(\boxed{\$2.5}\) and the rental cost for each video game is \(\boxed{\$5.25}\).
Step 1 ：Let's denote the cost of renting a movie as x and the cost of renting a video game as y.
Step 2 ：From the table, we can see that last month Dante rented 3 movies and 2 video games for a total cost of $18. This gives us the equation \(3x + 2y = 18\).
Step 3 ：This month, he rented 8 movies and 4 video games for a total cost of $41. This gives us the equation \(8x + 4y = 41\).
Step 4 ：So, the system of equations is: \[\begin{array}{l}3x+2y=18 \\ 8x+4y=41\end{array}\]
Step 5 ：Solving this system of equations gives us the solution \(x = 2.5\) and \(y = 5.25\).
Step 6 ：So, the rental cost for each movie is \(\boxed{\$2.5}\) and the rental cost for each video game is \(\boxed{\$5.25}\).
