Final answer:
To determine how many games Kartheek can buy, we need to subtract the cost of the video game system from the total amount of money he received and solve for the number of games. Kartheek can buy approximately 4 games with the money he received.
Step-by-step explanation:
To determine how many games Kartheek can buy, we need to subtract the cost of the video game system from the total amount of money he received. This can be represented by the equation:
Number of games x Cost per game = Total money received - Cost of video game system
Let's solve this equation:
x x $49 = $500 - $300
x x $49 = $200
x = $200 / $49
x ≈ 4.08
Kartheek can buy approximately 4 games with the money he received.
