Chapter 0, Problem 20P

To determine

To find: difference between average high and average low temperatures

Answer to Problem 20P

The difference between average high and average low temperatures is ${28.6}^{°}\text{F}$

Explanation of Solution

Given:

Average high temperature during May $={64.5}^{°}\text{F}$

Average low temperature during May $={35.9}^{°}\text{F}$

Calculation:

The formula for the difference is,

Difference = Average high temperature - Average low temperature

Thus, difference between average high and low temperatures is,

  ${64.5}^0\text{F}-{35.9}^0\text{F}$

So, this problem involves decimal subtraction.

  $\begin{array}{l}64.5\\ \underset{\_}{-35.9}\\ 28.6\end{array}$

Therefore, difference of given numbers is 28.6

Conclusion:

Hence, difference between average high and average low temperatures is ${28.6}^{°}\text{F}$
