Question

Find each percent of change round answers to the nearest tenth of a percent if necessary (25 is decreased to 18)

Answer 1

Answer:

$\%Change = -28\%$

Step-by-step explanation:

Given

25 decreased to 18

Required

Determine the percentage change

This is calculated as follows:

$\%Change = \frac{Initial\ Value - New\ Value}{Initial\ Value} * 100\%$

In this case:

$Initial\ Value = 25$

$New\ Value = 18$

So, the formula becomes

$\%Change = \frac{18 - 25}{25} * 100\%$

$\%Change = -\frac{7}{25} * 100\%$

$\%Change = -\frac{7* 100\%}{25}$

$\%Change = -\frac{700\%}{25}$

$\%Change = -28\%$

Hence, the change is 28% decrease
