Layla is a great singer. She is so famous she had 15 bodyguards at last night's concert. At her concert last month, she had 12. What is the percent of change?

1 answer

To calculate the percent of change, we use the formula:

Percent Change = ((New Value - Old Value) / Old Value) x 100

New Value = 15
Old Value = 12

Percent Change = ((15 - 12) / 12) x 100
Percent Change = (3 / 12) x 100
Percent Change = 0.25 x 100
Percent Change = 25%

So, there was a 25% increase in the number of bodyguards for Layla's concert from last month to last night.
