Question

Use the table to answer the question. Subject Number of Students English 6 Math 4 History 3 Science 5 Other 3 Mrs. Guajardo has 135 students taking her Algebra 2 class. She surveys the 21 students in her first-period class about their favorite school subject. Calculate the percentage of students in the sample who reported math as their favorite subject. Round your answer to the nearest whole number.

Answer 1

To calculate the percentage of students in Mrs. Guajardo's first-period class who reported math as their favorite subject, we first need to identify how many students from the 21 surveyed chose math as their favorite.

From the table:

- English: 6
- Math: 4
- History: 3
- Science: 5
- Other: 3

The number of students who reported math as their favorite subject is 4.

Next, we calculate the percentage of students who chose math:

\[
\text{Percentage} = \left( \frac{\text{Number of students who like math}}{\text{Total number of students surveyed}} \right) \times 100
\]

Substituting in the numbers:

\[
\text{Percentage} = \left( \frac{4}{21} \right) \times 100 \approx 19.05
\]

Rounding this to the nearest whole number, we have:

\[
\text{Percentage} \approx 19\%
\]

Thus, the percentage of students in the sample who reported math as their favorite subject is **19%**.
