1. The problem states that the temperature was initially $-7$ degrees and then rose by $80$ degrees. 2. To find the new temperature, we use the formula for temperature change: $$\text{New Temperature} = \text{Initial Temperature} + \text{Change in Temperature}$$ 3. Substitute the given values: $$\text{New Temperature} = -7 + 80$$ 4. Simplify the expression: $$-7 + 80 = 73$$ 5. Therefore, the new temperature is $73$ degrees. This means the temperature increased from $-7$ degrees to $73$ degrees after rising $80$ degrees.
