Use F = (9/5)(K − 273) + 32.
55 = (9/5)(K − 273) + 32 → (9/5)(K − 273) = 23 → K − 273 = 23·5/9 ≈ 12.78
So current T ≈ 273 + 12.78 = 285.78 K. Required is 307 K, so raise by 307 − 285.78 ≈ 21.22 K.
In Fahrenheit, ΔF = (9/5)·21.22 ≈ 38.2°F. The correct response: increase the room temperature by 38°F (to about 93.2°F).
