Answer 10

There is a formula for percent increase and percent decrease.

Answer 11

whats the first then?

Answer 12

Percent increase and percent decrease are NOT the difference in numbers.

Answer 13

Here is an example for you to understand the idea.
Let's say you start with 200. Then it increases to 300.
What is the percent increase from 200 to 300?

Answer 14

100 is the diff idk what your asking me

Answer 15

The increase (not percent increase, but just increase) from 200 to 300 is 100, correct?

Answer 16

yass

Answer 17

Correct. The difference, which is just the increase, is 100.
To find the percent increase, you need to find what percent 100 is of the original number, 200.
Since 100 is half of 200, 10 is 50% of 200.
That means from 200 to 300 it's a 50% increase.
That means that you increased 200 by 50% of 200 to get 300.

Answer 18

ok so 300 right ?

Answer 19

Here is the way to find a percent increase or decrease in general:

\(percent ~change = \dfrac{new ~number - old ~number}{old ~number} \times 100\)

Answer 20

stop making her beg for the awnser mane

Answer 21

just tell her

Answer 22

btw i just started im 8

Answer 23

whats the answer

Answer 24

idk use mathpapa

Answer 25

Here's how you use the formula.

An increase from 200 to 300 means that the old number is 200 and the new number is 300. Insert those numbers in the percent change formula to find the answer.

\(percent ~change = \dfrac{new ~number - old ~number}{old ~number} \times 100\)

\(percent ~change = \dfrac{300 - 200}{200} \times 100 = \dfrac{100}{200} \times 100 = 50\%\)

Answer 26

An increase from 50 to 90 is:

\(percent ~change = \dfrac{90 - 50}{50} \times 100 = \dfrac{40}{50} \times 100 = 0.8 \times 100 = 80\%\)

Answer 27

The answer to the first question is 80%.
Since the answer is positive, it is a percent increase.
If the answer is negative, it is a percent decrease.

Answer 28

Here is the second problem.
What is the percent decrease from 110 to 77?
Again, we use the formula. This time, we use 100 fro the old number, and 77 for the new number.

\(percent ~change = \dfrac{77 - 110}{110} \times 100 = \dfrac{-33}{110} \times 100 = -0.3\times 100 =-33\%\)

Since the answer is negative, the answer is percent decrease.
The answer is 33% decrease.
