Question

Veronica randomly surveyed a group of students to find out how they arrived at school that

morning. The data she gathered are in the table below.
HOW STUDENTS ARRIVED AT SCHOOL
Walked Car Bicycle
Number of Students
73
Bus
42
Which statement about the 540 total students at Veronica's school is best supported by
the data?
B
C
Many more students walk to school than arrive by car.
About 380 students take the bus to school.
Fewer than 20 students ride bicycles to school.
D
About 140 students walk to school.

Answer 1

B: About 380 students take the bus to school.

Explanation:

First, add all the numbers together.

8 + 7 + 3 + 42 = 60

Second, divide the total students at the school, 540, by the number Veronica surveyed, 60.

540/60 = 90

Thirdly, multiply each number by 9.

8*9 = 72

7*9 = 63

3*9 = 27

42*9 = 378

Lastly, use the numbers we just found to test the statements.

A is true, more students walk than arrive by car.

B is true, 372 is close to 380.

C is false, 27>20.

D is false, 72<140.

The problem says best supported, so the answer is B because B is more accurate than A.
