The temperature at the beginning of the day was 4°C. The temperature dropped 7°C by the end of the day. What was the temperature at the end of the day? Use the number line model to find 4 - 7



Answer :

Based on the temperature at the beginning of the day, and the change in temperature by the end of the day, the temperature at day's end was -3°C.

What is the ending temperature?

The temperature started at 4°C and then dropped during the day by a temperature of 7°C.

The temperature at day's end will therefore be:
= Beginning temperature - Change in temperature

Solving gives:

= 4 - 7

= -3 °C

In conclusion, the change in temperature would lead to an ending temperature of -3°C.
