C. $13$

D. $21$

Answer to Problem 24STP

The correct option is C. Number of people to drink the two or more soda cans per day in class $30$ are $13$ .

Explanation of Solution

Given:

  

Calculation:

The percent of children to drink the two or more soda cans per day is calculated as:

  $\begin{array}{l}{N}_{2+}\%=N_2+N_3+N_4+N_{5+}\\ N_{2+}\%=15+7+3+19\\ N_{2+}\%=44\%\end{array}$

Number of people to drink the two or more soda cans per day in class $30$ is calculated as:

  $\begin{array}{l}{N}_{2+}=N_{2+}\%\times n\\ N_{2+}=44\%\times 30\\ N_{2+}=13.2\\ N_{2+}\approx 13\end{array}$

Conclusion:

Hence, numbers of children to drink the two or more soda cans per day in class $30$ are $N_{2+}\approx 13$
