Answer 2

☯️GIVEN:

• The enrollment of students in a school in January 1970 was 850
• The enrollment of students in a school in January 1980 was 1,120

☯️FIND:

• Percentage increase for the enrollment

☯️SOLUTION:

We know that the enrollment in January 1970 was 850 and in January 1980 was 1,120.

So,

Increase Enrollment = 1,120 - 850

= 270 students

Percentage = $\bold{\frac{value}{total\:value}\times100}$

So, percentage of enrollment increased is

$\bold{ \implies \frac{270}{1120} \times 100 }$

$\bold{ \implies \frac{ \cancel{270}}{ \cancel{1120}} \times 100 }$

$\bold{ \implies 0.2410 \times 100 }$

$\bold{ \implies 24.1071\% }$

Hence, percentage of increasing enrollment of students is 24.1071%
