Answer:

80%

Step-by-step explanation:

To find percentage increase, we use the following formula:

Percentage Increase = [tex]\frac{New-Old}{Old}*100[/tex]

Here

New means the latest value (which is 18 dancers)

Old means the previous value (which is 10 dancers)

The Multiplication by 100 is to convert the decimal answer to percentage.

So, we have:

New = 18

Old = 10

Now we substitute and find:

[tex]\frac{New-Old}{Old}*100\\\frac{18-10}{10}*100\\\frac{8}{10}*100\\80[/tex]

So, there was an increase of 80%
