Answer 1

To find the temperature on Tuesday, you start with the temperature on Monday, which is \(-4°C\), and then apply the change of 13° colder.

Calculating the Tuesday temperature: \[ -4°C - 13°C = -17°C \]

So, the temperature on Tuesday is \(-17°C\), which corresponds to option C.

The correct answer is C. −17°C.
