Understanding Percentage Decrease in Attendance

The video tutorial explains how to determine the original attendance before a 3% drop, given the post-drop attendance of 2800. It involves setting up a percentage equation, converting percentages to decimals, and solving for the unknown using division. The final step includes rounding the result to the nearest whole number, concluding that the original attendance was 2887.

What was the attendance after a 3% drop?

• 2800

• 2700

• 3000

• 2900

If 2800 is 97% of the original attendance, what does this imply about the original attendance?

• It was more than 2800

• It was less than 2800

• It was 97% of 2800

• It was exactly 2800

Which variable is used to represent the unknown original attendance?

• y

• a

• x

• b

How do you convert 97% to a decimal?

• 0.97

• 0.097

• 9.7

• 97.0

What equation represents the relationship between 2800 and the original attendance?

• a + 0.97 = 2800

• 0.97 * a = 2800

• a / 0.97 = 2800

• a - 0.97 = 2800

What is the significance of the number 0.97 in the equation?

• It is the original attendance

• It is the attendance after the drop

• It represents the percentage increase

• It is the decimal form of 97%

What operation is used to solve for 'a' in the equation 0.97 * a = 2800?

• Multiplication

• Subtraction

• Division

• Addition

What is the approximate original attendance when rounded to the nearest whole number?

• 2888

• 2885

• 2887

• 2886

Why do we round the calculated original attendance to the nearest whole number?

• To match the format of attendance numbers

• To make it easier to remember

• To avoid decimals in attendance

• To simplify the calculation

If the original attendance was 2887, what would be the attendance after a 3% drop?

• 3000

• 2900

• 2800

• 2700
