Question

Find the percent change from the first value to the second. 30; 42​

Answer 1

The percentage change is a 40% increase.

Explanation:

Given

• Old value = 30

• New value = 42

To determine

The percent change from the first value to the second

Using the formula

Percentage change = [New value - Old value] / | Old value | × 100

= [42 - 30] / |30| × 100

= 12 / 30 × 100

= 0.4 × 100

= 40% change

= 40% increase

Therefore, the percentage change is a 40% increase.
