Final answer:
After purchasing three bus tickets, Aaron can buy four train tickets with his remaining budget of $520.
Step-by-step explanation:
To determine how many train tickets Aaron can buy after purchasing three bus tickets, we need to perform a series of calculations. First, we calculate the total cost of three bus tickets:
- Cost per bus ticket = $64
- Total cost for three bus tickets = 3 tickets × $64/ticket = $192
Next, we calculate the remaining amount Aaron has after buying the bus tickets:
- Total budget = $520
- Remaining amount after bus tickets = $520 - $192 = $328
Finally, we calculate how many train tickets Aaron can buy with the remaining amount:
- Cost per train ticket = $82
- Number of train tickets = Remaining amount ÷ Cost per train ticket
- Number of train tickets = $328 ÷ $82/ticket = 4 tickets (since Aaron cannot buy a fraction of a ticket)
Therefore, Aaron can buy four train tickets after purchasing three bus tickets with his $520 budget.
