Final answer:
To determine which option costs the least amount of money, we need to compare the total cost for each option. Option 2: Buy 2 and Get a 70% Off Mail-in Rebate costs the least amount of money with a total cost of $30.
Step-by-step explanation:
To determine which option costs the least amount of money, we need to compare the total cost of each option. Let's find the total cost for each option:
Option 1: Buy One Get One Free
For this option, you will pay the full price for the first game ($50) and get the second game for free. So the total cost will be $50.
Option 2: Buy 2 and Get a 70% Off Mail-in Rebate
For this option, you will buy two games, which will cost you 2 * $50 = $100. Then you will get a 70% off mail-in rebate, which means you will get a discount of 70% of $100, which is $70. So the total cost will be $100 - $70 = $30.
Therefore, the option that costs the least amount of money is Option 2: Buy 2 and Get a 70% Off Mail-in Rebate with a total cost of $30.
