Final answer:
After setting up and solving the equation based on the provided information, we find that Ticket to Ride costs $50 and Pandemic: Edition 2 costs $70.
Step-by-step explanation:
To solve this problem, we need to set up equations based on the information given. Let's denote the cost of Ticket to Ride as "x". According to the problem, Pandemic: Edition 2 costs "x + $20" more. We know that together the game cost totals $120. So, we can set up the following equation:
x + (x + $20) = $120
Combining like terms, we get:
2x + $20 = $120
Now, subtract $20 from both sides to isolate 2x:
2x = $100
Dividing both sides by 2, we find that x = $50. This means Ticket to Ride costs $50 and hence, Pandemic: Edition 2 costs $50 + $20 = $70.
The correct answer is a. Ticket to Ride costs $50, and Pandemic: Edition 2 costs $70.
