your answer to the nearest whole number if necessary.
10 ) 14 of the students in a algebra class passed a algebra test. if these students are 53.65%
of all the students in the class, how many students are in this algebra class? round your
answer to the nearest whole number if necessary.

Explanation:

Problem 9

Step1: Identify formula for percentage

To find the number of exhibits with monkeys, use the formula: \( \text{Number} = \text{Total} \times \text{Percentage (in decimal)} \)

Step2: Convert percentage to decimal

\( 76.00\% = \frac{76}{100} = 0.76 \)

Step3: Calculate the number of exhibits

Total exhibits = 50, so \( 50 \times 0.76 = 38 \)

Step1: Identify formula for percentage

Let \( x \) be the total number of students. We know that \( 53.85\% \) of \( x \) is 14, so the formula is \( 0.5385x = 14 \)

Step2: Solve for \( x \)

\( x = \frac{14}{0.5385} \approx 26 \) (rounded to nearest whole number)

Answer:

38
