Final answer:
Hans paid $92.39 for his trip.
Step-by-step explanation:
Hans paid for his trip by using frequent flier miles, but he still had to pay for fees and taxes. The equation given is y = $0.17x + $15.89, where x represents the distance Hans is flying and y represents the cost of the trip. To find out how much he paid for his trip, we need to substitute the given distance of 450 miles (x = 450) into the equation:
- Plug in x = 450 into the equation: y = $0.17 * 450 + $15.89
- Multiply: y = $76.50 + $15.89
- Add: y = $92.39
Therefore, Hans paid $92.39 for his trip.
