Final answer:
To find the price of one wii game, set up a system of equations and solve for the unknown variables.
Step-by-step explanation:
To find the price of one wii game, we need to set up a system of equations using the given information.
Let's represent the price of one Nintendo ds game as 'x' and the price of one wii game as 'y'.
We know that 3 ds games and 2 wii games were purchased, and the total cost was $169.
This can be represented as the equation 3x + 2y = 169.
We also know that one ds game and one wii game were being sold for a total of $70.
This can be represented as the equation x + y = 70.
Solving these two equations will give us the price of one wii game.
