The temperature is 2 degrees and drops to -15 degrees overnight. Write and then evaluate a subtraction expression to determine the change in temperature.

-17 degrees

Step-by-step explanation:

Given that:

Initial temperature = 2 degrees

Final temperature = -15 degrees

To Determine:

The change in temperature.

Solution:

First of all, let us have a look at the method for calculating the change in any quantity.

Let the initial quantity =

Let the final quantity =

Change in quantity = Final quantity - Initial quantity =

Here, we are given the quantity as temperature.

where degrees and

degrees

Therefore, the change in temperature = -15 - 2 = degrees
