The two-way table below shows the number of students in a school who bring their lunch and/or who ride the bus:

\begin{tabular}{|c|c|c|c|}

\hline Rode Bus & 40 & 35 & 75 \\
\hline Do Not Ride Bus & 55 & 2 & 57 \\
\hline Total & 95 & 37 & 132 \\
\hline
\end{tabular}

How many more students bring lunch than ride the bus?

A. 25
B. 20
C. 7
D. 3



Answer :

To determine how many more students bring their lunch compared to those who ride the bus, we need to identify the total number of students who bring their lunch and the total number of students who ride the bus from the given table.

Let's examine the table:

1. Total number of students who bring their lunch:
- The "Bring Lunch" column indicates that a total of 95 students bring their lunch (this includes both those who ride the bus and those who do not).

2. Total number of students who ride the bus:
- The "Rode Bus" row indicates that a total of 75 students ride the bus (this includes both those who bring their lunch and those who do not).

Next, we need to find the difference between the total number of students who bring their lunch and those who ride the bus:

[tex]\[ \text{Number of students who bring lunch} = 95 \][/tex]

[tex]\[ \text{Number of students who ride the bus} = 75 \][/tex]

[tex]\[ \text{Difference} = 95 - 75 = 20 \][/tex]

Hence, 20 more students bring their lunch than ride the bus.

The correct answer is:

[tex]\[ \boxed{20} \][/tex]
