Mrs. Smith has a total of 28 kids in her class. There are 5 more boys than there are girls. Write a system of equations to model this.

A. [tex]\(\left\{\begin{array}{l}b+g=28 \\ b=g+5\end{array}\right.\)[/tex]

B. [tex]\(\left\{\begin{array}{l}b+g=28 \\ b+g=5\end{array}\right.\)[/tex]

C. [tex]\(\left\{\begin{array}{l}b+g=28 \\ g-b=5\end{array}\right.\)[/tex]



Answer :

To model the situation where Mrs. Smith has a total of 28 kids in her class, and there are 5 more boys than girls, let's define the variables:

- [tex]\( b \)[/tex] represents the number of boys.
- [tex]\( g \)[/tex] represents the number of girls.

We know two things from the problem statement:

1. The total number of kids is 28.
2. There are 5 more boys than girls.

We can write these two statements as a system of equations:

1. [tex]\( b + g = 28 \)[/tex] (total number of kids)
2. [tex]\( b = g + 5 \)[/tex] (there are 5 more boys than girls)

So the correct system of equations to model this scenario is:
[tex]\[ \left\{ \begin{array}{l} b + g = 28 \\ b = g + 5 \end{array} \right. \][/tex]

This correctly captures all the given information about the relationship between the number of boys and girls in Mrs. Smith's class.
