Chapter 13.7, Problem 23STP

To determine

The number of children drinks two cans or less per day of soda from the following four options:

F. $5700$

H. $14060$

G. $8993$

J. $26,980$

Answer to Problem 23STP

The correct option is J. $26,980$ numbers of children drinks two cans or less per day of soda.

Explanation of Solution

Given:

Concept Used:

Number of people to drink the soda cans per day is expressed by using the following expression:

  $N_i=\frac{P_i}{100}\times N$

Where,

No of children participated in the study: $N$

The percentage of children for the drinking soda cans as per the given figure: $P_i$

Calculation:

Number of children to drink the two soda cans per day is calculated as:

  $\begin{array}{l}{N}_2=\frac{P_2}{100}\times N\\ N_2=\frac{15}{100}\times 38000\\ N_2=5700\end{array}$

Number of children to drink one soda can per day is calculated as:

  $\begin{array}{l}{N}_1=\frac{P_1}{100}\times N\\ N_1=\frac{37}{100}\times 38000\\ N_1=14060\end{array}$

Number of people to drink the zero soda cans per day is calculated as:

  $\begin{array}{l}{N}_0=\frac{P_0}{100}\times N\\ N_0=\frac{19}{100}\times 38000\\ N_0=7220\end{array}$

Hence, the total number of children who drinks two soda cans or less per day is calculated as:

  $\begin{array}{l}{N}_T=N_2+N_1+N_0\\ N_T=5700+14060+7220\\ N_T=26,980\end{array}$

Conclusion:

Hence, the total number of children who drinks two soda cans or less per day is $26,980$
