We need to solve problem (h) from the image. A refrigerator has a temperature of $7^\circ C$ below zero. Due to a power outage, the temperature rises by $4^\circ C$. After the power is restored, the temperature drops by $5^\circ C$. We need to find the final temperature.

1. Problem Description

We need to solve problem (h) from the image.

A refrigerator has a temperature of $7^\circ C$ below zero. Due to a power outage, the temperature rises by $4^\circ C$. After the power is restored, the temperature drops by $5^\circ C$. We need to find the final temperature.

2. Solution Steps

The initial temperature is $7^\circ C$ below zero, which can be represented as $-7^\circ C$.

The temperature rises by $4^\circ C$, so the new temperature is $-7 + 4 = -3^\circ C$.

The temperature then drops by $5^\circ C$, so the final temperature is $-3 - 5 = -8^\circ C$.

3. Final Answer

The final temperature is $8^\circ C$ below zero.

$-8^\circ C$
