Explanation:

Step1: Calcular la cantidad de horas transcurridas

El tiempo desde las 2:00 PM hasta las 6:00 PM es 4 horas.

Step2: Calcular la variación de temperatura

Como la temperatura disminuye 2.5°F cada hora y han pasado 4 horas, la variación es $2.5\times4 = 10$°F.

Step3: Calcular la temperatura final

La temperatura inicial era 7°F y ha disminuido 10°F, entonces la temperatura final es $7 - 10=- 3$°F.

Answer:

• 3°F
