Question

Last year there 520 students enrolled at Olsen Middle School..This year there are 572 students enrolled.What is the percent of increase in the number of students

Answer 1

Answer:

10%

Step-by-step explanation:

To understand the concept around percentage increase or decrease, we always state clearly the conditions.

Please always remember:

(Increase / Original number) * 100

Number of LAST YEAR enrolled students at Olsen Middle School:

= 520 Students

Number of THIS YEAR enrolled students at Olsen Middle School:

= 572

Difference in the number of students in both years:

= This year's students number - Last year's students number

= 572 - 520

= 52 students (Increase)

To solve for the percentage increase:

= (Increase / Last years Total) * 100

= (52 / 520) * 100

= 0.01 * 100

= 10 %

Percentage increase = 10%

Answer 2

Answer:

The percent of increase in the number of students is 10%.

Step-by-step explanation:

The percent increase in the number of students is the absolute increase divided by the number of students last year.

Last year: 520 students

This year: 572 students

Absolute Increase: 572 - 520 = 52 students

Percent increase:

$p = \frac{52}{520} = 0.1$

The percent of increase in the number of students is 10%.
