The temperature dropped 3C every hour for 5 hours right in integer that represents the change in temperature

-15°C.

Step-by-step explanation:

They tell us that the temperature dropped 3 ° C every hour, therefore, the temperature change every hour = -3 ° C

They also tell us the total number of hours during which the temperature was changed = 5,

We have to:

The total change in temperature = change over an hour * total number of hours:

TC = - 3rd * 5

TC = -15 °

Then we can affirm that the integer representing the temperature change is -15 ° C.
