Spotlight Dance increased the number of dancers on its competition team. Last
Nana76 [90]

Answer:

80%

Step-by-step explanation:

To find percentage increase, we use the following formula:

Percentage Increase = \frac{New-Old}{Old}*100

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:

\frac{New-Old}{Old}*100\\\frac{18-10}{10}*100\\\frac{8}{10}*100\\80

So, there was an increase of 80%

Hope this helps have a great afternoon:)

allsm [11]
Answer is to ask for brown rice instead of white rice.

Reason is brown rice is less refined and has more fiber to help you stay full and it has a lower GI index.

❌ he can ask for the tomatoes to be left out (tomatoes are healthy and good for you).
✅ he can ask for brown rice instead of white rice.
❌ he can ask for his tofu to be fried instead of grilled (fried is not healthier)
❌he can ask for fewer sprouts, peas, and cucumbers. (These are good for you)
