Question

Find the percent of change. Round to the nearest percent.

Answer 1

Answer:

-54.5%

Step-by-step explanation:

You will have to use this formula

$\frac{new value-oldvalue}{oldvalue}$

When substituted in you have $\frac{30-66}{66}$

30-66=-36

-36/66= -0.54 (54 repeating)

Then you have to convert this into a percentage, -54.54(repeating) percent

To the nearest hundredth you would round down to -54.5%.

It is a Decrease because it is negatated.
