Chapter 1.1, Problem 50E

(a)

To determine

To calculate: To find what percent is represented by the entire circle

Answer to Problem 50E

The entire circleis represented by $100\%$

Explanation of Solution

Given: The circle graph shows the percent of different animals sold at a local store in $1$ year

  

Calculation:

Entire circleis represented by $100\%$

(b)

To determine

To calculate: To find how the equation $7+9+5+48+x=100$ relates to the circle graph and to find how one can use this equation to find the percent of cats sold

  $\begin{array}{l}7+9+5+48+x=100\\ x=100-69\\ x=\end{array}$

Answer to Problem 50E

The percent of cats sold is $31\%$

Explanation of Solution

Given: The circle graph shows the percent of different animals sold at a local store in $1$ year

  

Calculation:

Given the equation is as follows:

  $7+9+5+48+x=100$

The above equation relates to the circle graph as $7,9,5,48,x$ are the percent of different animas sold at a local store and there sum is equal to $100$

On solving the equation:

  $\begin{array}{l}7+9+5+48+x=100\\ x=100-69\\ x=31\%\end{array}$

Conclusion:

Hence, thepercent of cats sold is $31\%$
