Example Questions

Example Question #91 : The Number System

On a particular November day, it is \(\displaystyle 65^\circ F\) and sunny in Tucson, Arizona. On the eastern side of the United States, it is \(\displaystyle -23^\circ F\) and sleeting in New Castle, Pennsylvania. How many degrees warmer is it in Tucson than New Castle?

Possible Answers:

\(\displaystyle 87^\circ F\)

\(\displaystyle 98^\circ F\)

\(\displaystyle 97^\circ F\)

\(\displaystyle 78^\circ F\)

\(\displaystyle 88^\circ F\)

Correct answer:

\(\displaystyle 88^\circ F\)

Explanation:

There are several ways that we could solve this problem. First, we can say that the temperature in New Castle is \(\displaystyle 23^\circ F\) below zero and in Tucson it is \(\displaystyle 65^\circ F\) above zero; therefore we can say:

\(\displaystyle 23+65=88^\circ F\)
