Question

One day the temperature started at -6°F and dropped 16° by the end of the day. What was the temperature at the end of the day?

Answer 1

See a solution process below:

Explanation:

Saying the temperature dropped `16^o` means it went down by `16^o`.

Therefore we need to subtract `16^o` from the starting point which was `-6^o`.

`-6^o - 16^o = -22^o`

The temperature at the end of the day was a cold `-22^o`

Answer 2

-22°F

Explanation:

The temperature starts off at -6°F.

By the end of the day, it dropped by 16°F. This means you have to add the dropped temperature to find the 'end of the day' temperature. By dropping 16°F, we can say that we have to add -16°F to the original temperature.

So,

-6°F + (-16°F) = -22°F
