1 answer

To find the current temperature, we need to subtract the change in temperature from the original temperature:

Original temperature: 26 degrees Celsius
Change in temperature: -15.5 degrees Celsius

Current temperature = Original temperature + Change in temperature
Current temperature = 26 + (-15.5)
Current temperature = 26 - 15.5
Current temperature = 10.5 degrees Celsius

The temperature now is 10.5 degrees C.
