which letter represents a 25° decrease from the given temperature?

Explanation:

Step1: Identify current temperature

The current temperature on the thermometer is $85^{\circ}$.

Step2: Calculate decreased temperature

Subtract $25^{\circ}$ from $85^{\circ}$, so $85 - 25=60^{\circ}$.

Step3: Find corresponding letter

The letter that corresponds to $60^{\circ}$ on the thermometer is B.

Answer:

B
