Question

Last year there were 20 students in Ms.

Berry's class. This year there are 28
students. Find the percent of change.
Round to nearest percent.

Answer 1

Explanation:

increase = 28 - 20 = 8.

% change = increase ÷ original × 100

= 8 ÷ 20 × 100

= 0.4 × 100

= 40%

∴ percentage change = 40%

Answer 2

Step-by-step explanation: old students- 20

New students- 28

Percentage of change= New students - old students/ Old students x 100

= 28-20/20 x 100

= 40%
