Question

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

Answer 1

`\%Change = -28\%`

Explanation:

Given

25 decreased to 18

Required

Determine the percentage change

This is calculated as follows:

`\%Change = (Initial\ Value - New\ Value)/(Initial\ Value) * 100\%`

In this case:

`Initial\ Value = 25`

`New\ Value = 18`

So, the formula becomes

`\%Change = (18 - 25)/(25) * 100\%`

`\%Change = -(7)/(25) * 100\%`

`\%Change = -(7* 100\%)/(25)`

`\%Change = -(700\%)/(25)`

`\%Change = -28\%`

Hence, the change is 28% decrease
