Concept Used:

Rules of Addition/ Subtraction:

• Two numbers with similar sign always get added and the resulting number will carry the similar sign.
• Two numbers with opposite signs always get subtracted and the resulting number will carry the sign of larger number.

Rules of Multiplication/ Division:

• The product/quotient of two similar sign numbers is always positive.
• The product/quotient of two numbers with opposite signs is always negative.

In order to find the cost of renting the system we have as shown below,

The price of one game $\$8.50$ and each pay $\$13.25$

Total payment

  $\begin{array}{l}13.25-8.50\\ =4.75\end{array}$

So the game system rent for 3 is below

  $\begin{array}{c}3\times 4.75\\ =14.25\end{array}$

Thus, the renting the system is $\$14.25$
