The change is ? By ?

Answer 1

The percent change from the first value to the second is 75 % increase

Solution:

Given that find the percent change from the first value to the second 40 and 70

To find: percent change

Percentage change equals the change in value divided by the absolute value of the original value, multiplied by 100.

$\text { percent change }=\frac{\text { final value - initial value}}{\text { initial value }} \times 100$

If the result is positive, it is an increase

If the result is negative, it is an decrease

Here initial value = 40 and final value = 70

$\text { percent change }=\frac{70-40}{40} \times 100$

$\text{ percent change }=\frac{30}{40} \times 100$

$\text{ percent change }=\frac{300}{4}=75$

Thus the percentage change is 75 % increase
