Question

Solve the problem.

All 37 of the students in a mathematics class attended class on Monday. On Tuesday only 25 students attended. What was the percent decrease?

52%

67.6%

32.4%

48%

Answer 1

The percent decrease in student attendance from Monday to Tuesday is 32.4%, calculated by finding the difference in attendances and dividing by Monday's attendance, then multiplying by 100.

Step-by-step explanation:

The task is to calculate the percent decrease in the number of students attending a mathematics class from Monday to Tuesday.

First, we find the decrease in the number of students, which is the difference between the attendances on the two days: 37 (Monday) - 25 (Tuesday) = 12 students.

Next, we find the percent decrease with respect to the original number of students (Monday's attendance). The formula to calculate the percent decrease is:

Percent Decrease = (Decrease ÷ Original Number) × 100%

Substituting the values we have:

Percent Decrease = (12 ÷ 37) × 100%

Percent Decrease = 0.3243 × 100%

Percent Decrease = 32.4%

Thus, the percent decrease in student attendance from Monday to Tuesday is 32.4%.

Answer 2

32.4%

Step-by-step explanation:

To find the answer we need to consider that 37 students are the total of students in math, so:

37=100%

Now, because only 25 students went the next day, the number of students that didn't attend is:

37-25=12

This means that 12 out of 37 students is the decrease number, which in percentage is:

(12/37)*100%=32.4%
