Question

Please answer with a step by step explanation. Thank you.

The original quantity is 10 and the new quantity is 13. What is the percent change? Is it an increase or decrease?

Answer 1

Change in amount / percent increase x 100
= 3/ 10 x 100
= 30%
The answer is 30%

Answer 2

the percent change is 30%

Explanation:

To find the percent change, you can use the following formula:

percent change = (new quantity - original quantity) / original quantity * 100

Plugging in the values from your question, we get:

percent change = (13 - 10) / 10 * 100 = 3 / 10 * 100 = 0.3 * 100 = 30

Therefore, the percent change is 30%.

To determine if this is an increase or decrease, you can compare the new quantity to the original quantity. If the new quantity is greater than the original quantity, then it is an increase. If the new quantity is less than the original quantity, then it is a decrease.

In this case, the new quantity (13) is greater than the original quantity (10), so the percent change represents an increase.
