Minimum number of Airbnb Experiences to exactly fill an X-hour layover

Live coding 2. Prompt: Given experience durations and total layover hours, all with at most 1 decimal place, return the minimum number of experiences needed to sum exactly to X, or -1 if impossible. Experiences may be repeated; use exactly all hours; minimize number of purchases. Function signature: enjoy_the_trip(experiences, hours). Examples include [3.0,2.0], 7.0 -> 3; [1.5,3.5,6.0], 15.5 -> 3; [6.0,7.0], 15.0 -> -1. This maps to unbounded coin change/minimum coins after scaling durations by 10 to avoid float errors.
